In a PQN PROC, in addition to the MV command, the IH command can do output 
conversions:

MV %2 ""
IH%1:G1*1:
Or input conversions:
IH%2;D;

PQN procs are supported in unidata for sure. Just wasn't sure if the 
conversions on the MV command work there.

You can use the universe proverb documentation as a starting point for working 
with procs in unidata, but there are a lot of differences, including some 
fundamental ones. For example, both PQ and PQN proc on universe use attribute 
marks to delimit fields in the buffers, but PQ proc in unidata uses the 
"standard" space delimiters.    The universe proverb manual doesn't mention 
conversions on the MV command
