Description

This instruction is used to duplicate the contents of the screen fields.

All the variables SeriesVarId whose contents can be duplicated must be indicated after this instruction.

 

In principle, this instruction is placed at the beginning of the VERIFICATION section.

If the duplication involves subfile data, this instruction must be placed after the MANAGE_SFL instruction.

 

If the field is in a subfile, the DUP key will have the effect of copying the field of the previous record.

In normal formats, the DUP key copies the last entered value in the field.
