No.

BUT you do need to manually set the length of the result field after the move:
MOVE FIXFLD VARFLD
EVAL %len(VARFLD) = %len(%trimr(FIXFLD))

BUT...you shouldn't be using MOVE in RPGIV at all...and you really
shouldn't be trying to use it with variable length fields.


You have to set the length before the move. If the length of VARFLD was zero before the move, nothing would get moved. (Or if less than the required length, not enough would get moved.)

Assuming there is some good reason for using MOVE with the varying field and not just using EVALR.
