Someone gave me an excellent course in variable and expressions.
Thanks to everyone for helping.

Craig,

I forgot to mention that the greater-than is in the variable in both cases. To see the content of a variable, I would use SHOWVAR instead of dereferencing the variable in another command. A dereferenced variable will be executed as you can see in the ECHO command. Escaping special characters is useful in some cases. It really depends what you want to do with the variable later on.

Thanks...François

Craig,

I think you need to "escape" the greater-than with an exclamation point as in:

FDE:SETVAR SPOOL_NBR "O1234"
FDE:SETVAR COPY_FROM,"awk '{$1 ='""; print }' " + RTRIM("!SPOOL_NBR") + ".OUT.HPSPOOL " +  ">"  + " " +  RTRIM("!SPOOL_NBR")
FDE:ECHO !COPY_FROM
<Displays nothing. A temporary file called O1234 is created>
FDE: !COPY_FROM
<Displays nothing. A temporary file called O1234 is created>

FDE:SETVAR COPY_FROM,"awk '{$1 ='""; print }' " + RTRIM("!SPOOL_NBR") + ".OUT.HPSPOOL " +  "!>"  + " " +  RTRIM("!SPOOL_NBR")
FDE:ECHO !COPY_FROM
awk '{$1 ='"; print }' O1234.OUT.HPSPOOL > O1234 FDE:!COPY_FROM awk '{$1 ='"; print }' O1234.OUT.HPSPOOL > O1234 Unknown command name. (CIERR 975)

HTH

Thanks...François

SETVAR COPY_FROM,"awk '{$1 ='""; print }' " + RTRIM("!SPOOL_NBR") &
                      + ".OUT.HPSPOOL " +  ">"   + " " +  RTRIM("!SPOOL_NBR") ECHO !COPY_FROM 

It all fails with the >
How do I pass the > as a string and not an operator?

Thanks!
