Well, that's my own and personal understanding of it. I never use PM as assembler, but MPASM.

I guess one day Melabs may release PM in 32bits, or just suggest to use MPASM instead OR have MPASM installed in.

In MicroCode Studio, click on View > Compile and program option >> Assempler and check 'use MPASM' box. That should do the trick... finger crossed.
Hi Steve,

It worked (I think)! I carried out your suggestion and the prog went off and found 'MPASM'. It couldn't find my programmer though (PICkit 2) but I guess that this is a seperate issue. I loaded one of the demo files and, after I made a few changes and re-named it, it went off and generated an 'asm' file. This opened fine in MPLAB IDE.

If 'PM.exe' doesn't work and I am using 'MPLAB' to generate code do I actually need to buy 'PICBASIC' or merely 'MicroCode Studio'? There's a big difference in price!!

Many thanks for your patient help, it is greatly appreciated.

Cheers.
