Hi, I have a question about accessing submissions using the &submission() function.
I am working on a problem interfacing with Geogebra that will have a variable number of submission inputs, depending on the randomization of the problem. The code in the customresponse section is relatively short and straightforward, so I just used an array to load the values. Someone at last year's conference suggested this approach, and it works well, creating an array of the appropriate size for the submission: [cid:image002.jpg@01D5F201.23A73F30] The code in the primary block of Perl script, however, is more complicated, so I have been using discrete variables with names that make it easier to read, follow, and troubleshoot the code: [cid:image006.jpg@01D5F201.23A73F30] I have found that I can include the unused variables, which in the above case are all of the variables beginning with $A2, and LON-CAPA just ignores those variables with no apparent ill effects. Is that a reasonable and "safe" way to write the code, or I am asking for trouble using this approach? Best regards, Gene L.
