RE: blank variable

One other thing to look at. Is there a program call between the population
and the write. I've seen cases where a program call caused an unrelated
field to change, the reason... The parameters where not matching between the
two programs, so while program 1 thought a field was 10 bytes program 2
thought it was 20 and clobbered whatever field was in memory after the field
that was passed. Strange but true. BTW, you will see this on the trace
output.

Just the usual, trace the variable, check to see if it is coincident
in a data structure, check to see if the record format is being reset,
check to see if it is duplicated in another input record.

Stuff like that.
