Back in the day, I typed the program in from the book and found it did not work. I wrote to Byte Books and got a reply that some of the program (one or two lines as I recall) had been lost during paste-up and did not make it into the book. I was the first to report the problem as everyone else that wanted to use the program had written in and got the correct program sent to them on a floppy. (Look for a gap in the line numbers between the bottom of one page and the top of the next.)
I don't remember what issues I had with differences in Pascals: I was using Texas Instruments TI990 minicomputer Pascal, but I did get it working.

See if this link works...
There should be two copies of the BYTE Pascal APL i found a few years ago
which had come from the owners i think ( not from the scanned BYTE book ).

This is Charles Richmond... yes, the OP of the original question
above... Thunderbird seems to have messed up the attributions badly.
I went through the listing of APL in Pascal in the BYTE book. The only
place that seems to have a line number gap between pages is between
pages 314 and 315 in the function DOP. On page 330, there is an odd
blank line between lines 31030 and 31056 in procedure PARSE.
If you can *not* remember the correction to make, can you make your good
Pascal source available for those of us who *never* got the corrections
from BYTE???
> I don't remember what issues I had with differences in Pascals: I was using Texas Instruments TI990 minicomputer Pascal, but I did get it working.
With some thought and care, you *can* write portable Pascal code. One
thing is to avoid the use of ord() on the character set and avoid the
use of chr().

Sounds like you need a "lint" for Pascal. Goog turned up ambiguous results,
but it sounds like there isn't one. Might be a good project for some Pascal
enthusiast.

I found my file for this project. The letter is from Alan Kaniss, one of the authors. It is hand-written on note paper from Feb 22, 1982. The missing line is line 31040: "ELSE RETURNTOCALLINGSUBR". I had forgotten that the machine readable form others got was a tape not a floppy disk.

Thanks much for the Pascal source correction for APL in Pascal!!! I was
one that "fat fingered" (i.e., typed in myself) the entire Pascal
source program. Although some may have gotten the source on digital
media from BYTE, I know I am *not* the only one who typed the dang thing
in!!! :-)
This fix should be on a web page and I plan to create a small web page
explaining this fix. Thanks again!!!

Robert, sinc you found your APL in Pascal project file... can you post
which issue of BYTE magazine contained the correction you gave??? My
BYTE magazines are accessible in pdf form, and seeing the printed
correction would probably be helpful...

I don't know if the correction ever appeared in Byte magazine. I'm not sure if they were even aware of the error until long after the book came out. My letter to Alan that generated the reply mentioned earlier, was about two years after the book came out and I'm not sure he was aware of the error until I brought it to his attention. (I think the reply to my letter to Byte books told me I would have to contact the authors.) My letter to Alan and the other authors had narrowed down the problem such that I knew the missing line number and that it was an "ELSE" clause, so it would be easy for him to look up the line. There may be other errors that are more subtle in their effects when trying to execute the program, but I didn't ask and Alan didn't volunteer.

(I think the reply to my letter to Byte books told me I would have to contact the authors.) My letter to Alan and the other authors had narrowed down the problem such that I knew the missing line number and that it was an "ELSE" clause, so it would be easy for him to look up the line. There may be other errors that are more subtle in their effects when trying to execute the program, but I didn't ask and Alan didn't volunteer.

You mentioned in an earlier post that some people received media (tape
or floppy disk) with a corrected version of the Pascal APL scanner. How
did you find out about this???
Did Alan Kaniss mention the media copies of the Pascal source to you???

My letter to Alan that generated the reply mentioned earlier, was about two years after the book came out and I'm not sure he was aware of the error until I brought it to his attention. (I think the reply to my letter to Byte books told me I would have to contact the authors.) My letter to Alan and the other authors had narrowed down the problem such that I knew the missing line number and that it was an "ELSE" clause, so it would be easy for him to look up the line.

Yes, it was Alan's letter that mentioned the tape copies when he talked about nobody before me having typed it in from the book and then writing to him, wondering about the error/missing line. (The idea of floppies came from my mis-remembering what the letter had said. When I found it, I corrected myself to tapes.)
