DSQ20409 &V1 is not allowed in the &V2 &V3 command.
Explanation
When global variable DSQEC_SAV_ALLOWED is set to &V4 and DSQEC_SAV_LOADER is set to 1, you cannot specify the &V1 keyword in the &V2 &V3 command.
User response
If you want to use the &V1 keyword with the &V2 &V3 command, set the DSQEC_SAV_ALLOWED global to the appropriate value and set DSQEC_SAV_LOADER to 0. Then issue the &V2 &V3 command again.
