<QUOTE>
I have an unusual occurance of the W559 error message and I hope someone out there can give me some insight as to a solution.



The code segment is as follows:



READ RECORD FROM FILE, RECORD_KEY THEN

   VARIABLE=TRIM(RECORD:' ':RECORD:' ':RECORD)

END ELSE

   VARIABLE='

END



The segment works for all the records it reads but one. When I edit the offending record, it appears normal. The TRIM function is used repeatedly in the program. The FILE  is indexed (Btree) and has the SI.MFS in it.



The program consistently breaks on the same record with the W559 "Cannot continue. An attempt was made to execute a null ("") program.".



Any suggestions would be a big help.



TIA,



Dick Trimble

<QUOTE>It's embarassing. I left a colon out of the trim statement:

ANSWER= TRIM(RECORD:' '^ECORD:' ':RECORD)

I put the ^ at the point of the missing colon. The program worked fine until RECORD was populated. Then it blew up.

<QUOTE>Yes forgotted colon is one of the most often typoes.

You must appropriately translate the error message to find it:)
