You were right Rob, the path was wrong. I have F:\DOSBOX as the root directory but use Mount F F:\DOSBOX So I should have had PATH F:\PALASM\EXE SET PALASM=F:\PALASM\ Using that, the Minimize Boolean option seems to work. And the F3 now explains errors. Next question, Could you write the equations for mA0 and /msXTRQ for me from the attached figure. I cannot figure out how you get more than one layer down without using brackets in these equations.

I have: PALASM.EXE is in J:\PALASM\EXE PDS files are in J:\S100 Environment variables are: PATH=J:\PALASM\EXE PALASM=J:\PALASM\ The trailing slash on PALASM variable is important - but you seem to have that correct. After compiling, there is an note at the bottom of the screen about: <F3>Help-errors When the path is wrong and I press <F3>, I get a notice about which EXE palasm can't find. Rob.
