Background: I wrote a arexx script that uses rexxarplib.library 3.0 and it works find on my Amiga 2000 with ADOS 2.04. Problem: When I put the script and rexxarplib 3.0 on a friends Amiga 4000 ADOS 3.0 it will not run. The rexxarplib 3.0 is not getting loaded because the system thinks that rexxarplib 3.0 is version 1.0. When I type "version libs:rexxarplib.library" it returns with version 1.0. I made sure that there were no other versions of the rexxarplib on his machine and I know that I had the right version because I copied it to disk and checked it on his wife's Amiga 600 (A family of Amiga computers 🙂 ) and version return 3.0. Here the line from my arexx script that loads the rexxarplib check=addlib("rexxarplib.library",0,-30,0) So any suggestion.
