Hi all,

I have installed two versions of PBP in my computer, 2.50c and 2.60c. Whenever I need to use either one I would go to the "Compiler" tab in the "Compile and Program Options" in Microcode Studio and chose either one of them.

Now, I have some 18F4550 programs in PBP 2.50 that are working fine and I would like to keep them the way they are. They require MPASM v8.15 to assemble, which is what I have installed in my PC. I believe newer versions of MPASM won't work with PBP 2.50. Lately, I have been working in a project with a PIC16F1939 that requires PBP 2.60. The old version (v8.15) of MPASM that I have won't work with this chip. I need to have a newer version of MPASM installed.

Now comes my question. Can I install a newer version of MPASM in a different folder and use either one of them as I need them by selecting the appropiate folder in the "Assembler" tab in MCS? Does anybody else do this? Is there a workaround for this issue?

Thank you all for your help,

Robert
