Ken,

I had used the debugger ot check on the value of sub.  In the main
processing table, at each break level reached from 1 to 5, sub would be set.
In the make_csv processing table, the program should branch to the proper
subroutine based on the value of sub.    Is it possible that setting this
value at a break point in an output and then transferring processing to a
called table is causing the value to clear?

As I indicated, I declared global in the main program, then tried to
make_csv and then finally in the auto processing table as a last resort.
That is where when the value of sub held between processing tables.
