Hey,
I'm trying to make a GOTO statement that says:
If field X exists in the held file then goto here, else goto there. Is there an easy way to do this?

How many rows are there in the hold file? You could write a flag to a SAVE file, -READ it into an amper variable and then use DM looping or GOTO to accomplish your needs.

If you are trying to determine if a particular column exists in a hold file, then use:
TABLE FILE SYSCOLUM
PRINT NAME
WHERE TBNAME EQ 'Hold File Name'
WHERE NAME EQ 'Column Name'
ON TABLE SAVE
END
-RUN
-IF &LINES GT 0 THEN GOTO ...

Do you mean: "If field X has a value?" If so, then Ginney plan should do the trick. However, if you mean "Does field X exist in a file?" then Waz's plan should work. But, you should already know if the "field" exists as it's part of your TABLE FILE request. Otherwise, I'm confused... Confused
