I have just tried this - Dilwyn's program will not work in anything less than 640K on q-emulator (I don't know if the unregistered version accepts this).
DILWYN - there is an issue with your program and in fact the file it creates does not work....
The original unzip program should be about 60K.
However, the SuperBASIC listing (unzip532_bas) says that there are a total of 54230 words (!)
It would also be better if the convertor created a BASIC program using LONGWORDS (4 bytes) to start with, then just oddwords, and oddbytes for the end - this would speed up the conversion process and make the overall basic program shorter (presuming the longwords can be stored in the DATA statements that is...)
In any case, I get an exception error in q-emulator when I try to EXEC the resulting unzip532_exe program - no idea why
Finally, TECHY - there is another copy of unzip on Dilwyn's site, specifically for Q-emulator - have a look on the page
http://www.dilwyn.me.uk/arch/index.html - towards the bottom you will find qemulator unzip.
