Can CL write to a disk file

Is there a command like SNDF that will work to a disk file?  V5R3.

Trying  workarounds like
  CHGVAR VAR(&OUTQFIX_OUTQ) VALUE('A')
  CHGVAR VAR(&OUTQFIX_AUTHLIST) VALUE('A')
  CHGVAR VAR(&OUTQFIX_CHANGED) VALUE('A')
  CHGVAR VAR(&OUTQFIX_MSGID) VALUE('A')
  STRQMQRY QMQRY(OUTQFIX) +
         SETVAR((OUTQFIX_OUTQ &OUTQFIX_OUTQ) +
                (OUTQFIX_AUTHLIST &OUTQFIX_AUTHLIST) +
                (OUTQFIX_CHANGED &OUTQFIX_CHANGED) +
                (OUTQFIX_MSGID &OUTQFIX_MSGID)) 
Which executes
INSERT INTO OUTQFIX 
VALUES(&OUTQFIX_OUTQ, &OUTQFIX_AUTHLIST, &OUTQFIX_CHANGED,
       &OUTQFIX_MSGID) 
But I get stupid messages like:
CALL ROB/TESTFIX 
   215 - STRQMQRY QMQRY(OUTQFIX) SETVAR((OUTQFIX_OUTQ 'A') 
  (OUTQFIX_AUTHLIST 'A') (OUTQFIX_CHANGED 'A') (OUTQFIX_MSGID 'A'))
Column A not in specified tables. 
RUN QUERY command failed with SQLCODE -206. 

And I'm just plain disgusted playing the apostrophe game.
