Hi,
I don't know where I can see the version of MPASM.
You can see which version of MPASM you're using in the progress window during the assembly process:
Name: MPASM 1.PNG Views: 405 Size: 9.3 KB

If, for some reason you don't see that you can always start the MPASM GUI application (MPASMWIN.exe) in the MPASM installation folder and see it there:
Name: MPASM 2.PNG Views: 439 Size: 50.6 KB

I use under (at the moment) 600 words when there is 2k in PIC12LF1552.
Yes but are you sure that you're actually compiling for the 12LF1552 and not for another device, by mistake. Are you using MicroCodeStudio, do you have the 12LF1552 selected in the dropdown list?

Before you upgrade to PBP3 (which I highly recommend anyway) you can try replacing the MPASM .inc file with the one in my previous post. Make sure you save the old one.

/Henrik.
