During a recent programming session, I was trying to type INVERSE characters, and the worked fine in capital letters, but lowercase letters got screwed up, so the word "Name" in inverse looked something like "N%&!" (in inverse letters of course). Anyone knows what causes this phenomena, and better yet, how to fix it? ------- ******************************************************************* Joe Carlin Don't Panic! ud041948@ndsuvm1.bitnet "I seem to be having this terrible difficulty with my lifestyle." - Arthur Dent, HGTTG *******************************************************************

However, a stock Apple ][+ (and I think also an unenhanced Apple //e, but I might be wrong) do not support inverse lower case letters in their character set, or flashing lower case for that matter. This is because the normal ASCII character set is 128 characters in size (including control characters), so to include both inverse and flashing modes they had to restrict the available number of characters to 64 for each mode. Besides, the Apple ][+ doesn't have normal lower case either, for no good reason :-) The Apple //e is suppose to have an extended character set (called mousetext or something) in which inverse lower case appears. However, since I only own an Apple ][+ I'm not an expert on how to invoke the additional characters. Someone else with more knowledge will have to step in with that information... </\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\></\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\> < Philip J.

Mousetext and normal. To display inverse lowercase at all you need to be in mousetext mode, so if it gets turned off, all you will see is the same characters from the normal set, which happen to be flashing symbols and numbers. To turn mousetext back on, just store something into $C00F. Or you can "PRINT CHR$(27)" from BASIC. UUCP: crash!pro-grouch!rond ARPA: crash!pro-grouch!rond@nosc.mil INET: rond@pro-grouch.cts.com

The phenomena is caused because the Apple // wasn't designed to print lower-case letters in inverse. You'll notice a similiar phenomenon when using flashing characters as well. As far as fixing it, it would be helpful to know which Apple // you had. At least for the //e and possibly //c & //c+ (I don't know about the IIgs), you should simply turn on the 80-column card (provided your //e has one). Then of course, you're in 80 columns and don't want to be there, right? At that point, I think you print a chr$(17) (ctrl-Q, right?) to put it into 40 column mode, using the 80-column card. If you do it correctly, your lower-case inverse characters will show up exactly as you would like them to be! Bill Ung ung@felix.UUCP

Okay, I'm sorry for not being more specific the first time, but here goes: Me and a friend have been working on this program. We're using an Apple IIGS with a 45 Meg hard drive, and the program runs in 40 column mode. We wrote a line that looks something like this: 3030 INVERSE : PRINT "Name:" Well, it's in inverse alright, but the lowercase characters get screwed up, and look something like "N%&!" in inverse characters (and no, they aren't mousetext, I know what mousetext looks like). It seems to me that BASIC is trying to shift the character's bits (one of them, I haven't really looked at the ascii chart to find out), but not the right one(s). Something may have done this earlier in the program (the things a monster, a few thousand lines of code get run before this) but is there a ?chr$(x) command that turns this off? We've tried a few, but no avail. ------- ******************************************************************* Joe Carlin (FWA) Don't Panic! ud041948@ndsuvm1.bitnet "I seem to be having this terrible difficulty with my lifestyle." - Arthur Dent, HGTTG "Hello, I know that you've been feeling tired.

[...] I believe the previous responses to your first message were correct, but I didn't study them too closely. There are TWO character sets available. The standard one has flashing characters, but it does *not* have inverse lower case! The other one, which you WANT, is the one that has MouseText in it. It also happens to have inverse lowercase letters in it. If you turn on the 80-column firmware, even if you go to 40-column mode with the firmware still on (a solid cursor instead of a checkerboard cursor) you will get lowercase letters juse fine. The 80-column firmware *does* do some shifting-around of the character codes to make things work right. If you do this, life will be Good for your inverse lowercase letters: 100 PRINT CHR$(4);"PR#3" 110 PRINT CHR$(17); : REM switch to 40-columns leaving the 80-col firmware ACTIVE! -- David A.

In-Reply-To: message from UD041948@NDSUVM1.BITNET To print inverse characters in 40 column mode on a IIGS, do the following: 10 PRINT CHR$(4)"PR#3" : REM Turn on 80-column mode 20 PRINT CHR$(17) : REM Switch to 40-column mode PRINT CHR$(18) switches back to 80-columns 30 INVERSE : PRINT "Hello" : NORMAL Running this program will print your 40-column text in inverse the way you want them to. -- Mark

Yes, there is documentation available. NO, it is not in a tech note. The standard one was documented in the original Apple II Reference manual. Both standard & mousetext are documented in the Apple //e Technical Reference and the Apple //c Technical Reference. Getting the alternate character set by turning on the 80 column firmware (whether or not you use 80 columns) is documented in the manual that comes with the //e's 80 column card... I have one somewhere. It is probably also documented in the IIgs Hardware & Firmware references, but I hardly ever refer to that section so I don't know what kind of treatment they give it.

Not all 80 column cards work the same. At my old high school, there were at least three different things you had to try to get some things to work, since not all of the IIe's had the same card, and not all of them were the same model (from Rev. A unenhanced to Platinum IIe's). There are discrepancies between cards... even Apple's. _____________________________________________________________________ | __ ___________ __ | | | /_/\/_/_______\_\/\_\ | Hammer's first law of Macintosh usage: | | \ \_\ \__ __/ /_/ / | ____________| | \ __ \ | | / __ / | System errors occur. | | | \_\/\_\|_|/_/\/_/ |____________________________| This space | | / /_/ /| |\ \_\ \ | | intention- | | /greg@hoss.unl.edu\ | "This data is raw!" ___ | ally left | | /_/ /_/_______\_\ \_\ | \-\|/-/ | blank... | |___________________________|____________________________|____________|

The card itself has no ROM on it, just 1K or 64K of RAM (1K on the regular 80-column card, 64K on the "extended" 80-column card). These days you can't buy the 1K version, which had only enough of the "auxiliary bank" of RAM for the text screen. The difference was just that some of your Apple IIe machines were "enhanced" and some were not.

Lyons, Apple Computer, Inc. | DAL Systems As far as inverse characters are concerned, both the "enhanced" and unenhanced IIe machines were capable of inverse lower case. MouseText is an addition which is not necessary for inverse lower case. Referring to your IIe reference manual will reveal a soft switch which will enable the alternate character set (including inverse lower case and sometimes MouseText), although the 80 column firmware will probably reset this switch without warning. The default text ROM soft switch setting enabled the II+ character set, which allows (in upper case characters) 64 inverse, 64 flash, 64 normal, 32 control and 32 normal lower case. There was not enough room for inverse lower case, so the IIe has a second set of 256 text characters which do not include FLASHing text. At first, only 32 were used for inverse lower case, but then the //c added 32 MouseText characters in the space where inverse upper case was repeated. An interesting side note (well, it was interesting to me): The older Wizardry games actually stored control character codes into text screen memory (i.e. hex codes $80 through $9F), even though these codes were never used by the normal Apple ROM COUT routines. I found this out on my II+ after I got the bright idea of using codes $80-$9F for my own inverse lower case (available at the same time as FLASHing, I had already added normal lower case with the proper ASCII codes of $E0-$FF). $80-$9F is essentially a wasted area of text ROM, so I didn't think it would hurt. Apparently, at the time Wizardry was written, there were lower case adaptors which used codes $80-$9F for lower case. I don't see why they chose to locate lower case characters at codes which were not ASCII standard (which caused the software to convert text files from other computers), but there is the advantage that machines without the lower case ROM would see upper case normal characters for codes $80-$9F. I guess that is an important feature, since this thread started when someone got funky numeric/special characters instead of lower case, because their character generator ROM was not set right.
