Re: [N8VEM-S100:3197] Re: GAL's and PALASM

I think we have the same directory layout but I've
mounted my "J drive" differently.

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.

It's been so long ago since I did that MSDOS path stuff!

Here is how I actually have my PALASM4 setup
It's on drive F:
The actual PALASM.EXE file is in the directory
F:\DOSBOX\PALASM
  That directory has sub directories
\DAT
\EXAMPLES
\EXE
\DOC
\S100  <- my GAL .PDS files

These directories were setup that way during the install (except the S100 one).

The only PATH & SET scripts I have are:-

PATH F:\DOSBOX\PALASM\EXE;F\;"%PATH;F:\DOSBOX\PALASM4\EXE"
SET PALASM=F:\PALASM\

Does seem screwed up Rob, now that I see it.
What do you have?

John

Bob, I'm just learning how to use PALASM4.  What I'm trying to figure
out is how to emulate in software the circuit attached here:-


Funny.   I was going to follow up on this.

But first I wanted to play with some of my 'known good' Heath H89 PAL designs.  To my surprise, PALASM4 didn't generate a .JED file...

Once I set the DOS PATH statement correctly, everything worked.

The executable sequence should be:

PARSE
BPP
EXPAND
BPP
MINIMIZE
PALXPT

With the path is not set correctly, PALXPT does not execute and the JED file is not created.

Can you verify?

I'll follow-up on the memory decoder question soon.

Rob.
