Hi. I am a little stumped, so I figured I'd ask the net... I wrote a nifty (I think 8-) ) stack for keeping track of my music col- lection and one to keep track of my library. One of the buttons in each stack looks at all the cards and determines which items at any particular time are out on loan to someone. This can be useful if I need to "recall" a book or cd, or whatever, or to remind someone to return something they borrowed 6 monthsago.. My problem is that the button contains the following script: (in part) repeat with the number of cards of this bkgnd ...do the checking end repeat Problem is, this doesn't work, and HC chokes on the "of this bkgnd". For my music stack this isn't a major problem... I only have one bkgnd, so I just took out the "of this bkgnd" part of the button script. that works fine. However, I have TWO backgrounds in my library stack... taking out the "of this bkgnd" results in the button repeating for the number of cards in the ENTIRE stack! Needless to say, this results in say, a single item on loan being "found" and reported too many times! I tried changing to "with this bkgnd" or "in" or etc., ad nauseum, to no avail. Can anybody tell me how to only repeat for the number of cards in a single background??? Alternately, how do I determine the "number of cards in bkgnd "X" "??? thanks for any info...

Yes, the "the number of cards" construct only works for the total number of cards in the stack, so you can't modify it with "of this bkgnd". > I tried changing to "with this bkgnd" or "in" or etc., ad nauseum, to >no avail. Can anybody tell me how to only repeat for the number of cards >in a single background??? Alternately, how do I determine the "number of >cards in bkgnd "X" "??? Try something like this: go first card of bkgnd "Whatever" put short id of this card into firstCard ...do the checking go next card of this bkgnd repeat until short id of this card is firstCard ...do the checking go next card of this bkgnd end repeat This should work but is on the slow side. If you have a field on the cards that contain the date the book was loaned out, and empty otherwise, then you can search for something like a comma in that field. go first card of bkgnd "Whatever" find chars "," in field "Loaned Date" if the result is not empty then ... nothing on loan end if put short id of this card into firstCard ...do whatever go next card of this bkgnd find chars "," in field "Loaned Date" repeat until short id of this card is firstCard ...do whatever go next card of this bkgnd find chars "," in field "Loaned Date" end repeat This is much faster if most of your library isn't loaned out.

Sometimes you have to put a quantity into a container all of its own to use it in a repeat statement. Try something like: put the number of cards of this background into NumbCards repeat with NumbCards ... end repeat Jan Harrington, sysop Scholastech Telecommunications UUCP: ihnp4!husc6!amcad!stech!sysop or allegra!stech!sysop BITNET: JHARRY@BENTLEY ******************************************************************************** Miscellaneous profundity: "No matter where you go, there you are."

There is no such thing as "number of cards in <bkgnd>" yet. The "number of cards" function assumes you mean the number of cards in the whole stack. There is no way to determine how many cards there are in a particular background without stepping through and counting them. As it happens, I spent yesterday at Bill's house adding a few new features, one of which was "number of cards in <bkgnd>". Don't ask me when this will ship or what else will be new because I can't talk about either topic. Dan.

I have not confirmed this, and it may very well be true. However, there is a more basic problem in the original example not yet mentioned: The "repeat with..." is to be used with a varible counter the same way a for loop is traditionally used. It might help to change the repeat loop to: repeat for <value> end repeat to see if this produces the desired results. John Gilbert -- John Gilbert !trwrb!felix!john
