Not sure this is the place to post this, but I was getting this (DBPRO Label error fix 1, imaged attached) error when I tried to create (compile) an exe for FPSC-MapEditor (english).dbpro
Line 50 reads: 'gosub _saveload_savebox_init' (DBPRO Label error fix 2, imaged attached) and I eventually figured the '?' in the error referred to the subroutine referenced after gosub, so I added an empty dummy subroutine after the gosub and I got to move on. (DBPRO Label error fix 3, imaged attached).
This probably isn't more than a band aid fix, but I had to intuit this much on my own, so hopefully this will help future google searchers understand what's going on, as I wasn't having any luck when I was searching.
If anyone knows where the subroutine this line is supposed to find is, I'd be happy to learn more. I'm not familiar with BASIC languages, but I know others and I'm always looking to expand my linguistic knowledge.
Take care all!
