Thanks. That does make sense, and I did indeed need a refresher course.

I noticed the announcement of your conference

Have you checked Jim Hurley stacks?

Hi Al.
Yes. I saw this mistake several times. The misleading thing is, TMHO,
the name "transformation matrix" for [a,b,c,d,e,f] (because the listing
is pairwise for columns, as you now describe, and not for rows).

Al, your script is wrong. You are building the matrix in a wrong way.
It is no bug! With your 'workaround' you point yourself to the lines
where you did make the mistake.

Hi Al.
This is not a bug, your script is wrong.
If TM is a,b,c,d,e,f then you have to do
put item 1 of pArgs into tMatrix[0,0]
put item 2 of pArgs into tMatrix[1,0]
put item 3 of pArgs into tMatrix[0,1]
put item 4 of pArgs into tMatrix[1,1]
this yields correct results.
