With DOS 3.2 I used a program called Setpath.exe.This program had one create a an ASCII file that only had the path in it and mine was about 300 bytes. The latest version is Setpth13.ZIP.You can get it from most BBS's. It has been revised to work with DOS 3.3 and 4.x . You can also get the program for $ 15.00 from: Covici Computer Systems 220 Dry Mill Road SW APT H Leesburg, VA 22075 --- ~ DeLuxe 1.11 #1435 jack.lupic@canremote.uucp

Sadow sadow@ncsatl.uucp replied: ss>The problem is you are running out of environment space. Check ss>your DOS manual for the correct syntax, but you need the following ss>you CONFIG.SYS: etc. I disagree. Under no circumstances can you expect *any* PC/MS DOS command longer than 127 characters will ever be read, even a PATH statement. This limit is totally independent of your config. Assuming that your command environment is big enough to support a 127 character PATH variable, you will still need to shorten it to that length or less! To do this, try one or the other of: Plan A: ^^^^^^ 1. Create a directory in c:\ called C:\BATCH 2. Have PATH=C:\BATCH;and then the others 3. Write some batch files to run your applications and put them in the batch directory. A strong reliance on Batch files could make things alot easier and dispense with some of your PATH needs. Remember that you do not need PATH=C:\WP50 to run word perfect, the line C:\WP50\WP %1 in a batch file does the same thing without necessitating the path statement. Plan B: ^^^^^^ 1. Have the statement LASTDRIVE=Z in config.sys 2. In autoexec.bat the following commands (assuming no extended partitions or device drivers are present) path=c:\doscom (where your dos utilties are) subst d: c:\batch subst e: c:\wp50 subst f: c:\utils subst g: c:\doscom subst h: c:\lotus subst i: c:\whatever\whoever\whenever path=d:\;c:\;e:\;f:\;g:\;h:\;i:\ Substitute your own choices. If you already have a drive d: or e: etc., start your subst's with e: or f:. Be aware that the more items in your path statement (the more file directory entries requiring searches), the slower your external commands will be found. Ensure that your BUFFERS statement in config.sys is 15 -- 30 especially with Plan B. Plan A is usually the most efficient over all, in my opinion. --WmP-- --- ~ DeLuxe 1.11a20 #3744 william.pipher@canremote.uucp
