Syntax

REVERSE_IMAGE Option SeriesVarId Transaction

Description

This instruction is used to condition a screen field display. A DDS screen attribute DSPATR(RI) is generated for all fields SeriesVarId indicated after this instruction. The attribute is preceded by an indicator in the screen file; this indicator is then activated by the program after the instruction is executed.

Whenever this instruction is used without *ON or *OFF, it is deactivated after each screen reading (indicator reset to 0), as well as by the instructions END_MANAGE_SFL and END_ADD_SFL when placed in a MANAGE_SFL/END_MANAGE_SFL or ADD_SFL/END_ADD_SFL block.

It is only possible to mention a transaction number if this instruction is used with *ON or *OFF.

When the instruction is used with *ON, it remains activated until executed with *OFF, for the same group of variables.

Notes:

• • A variable used with a group of variables must always be used with this same group.
  • For a specific variable, this instruction cannot be used once with *ON or *OFF and another time without *ON or *OFF.

REVERSE_IMAGE *ON ZORDER_NBR ZORDER_DATE ZORDER_CUST_COD
