The OVERLAY option specifies a catalogued subroutine to emit a graphical page overlay.

 

 

Format

 

OVERLAY subr.name

 

where

 

subr.nameis the name of a catalogued subroutine.

 

 

The OVERLAY option allows a report to include a graphical overlay to draw a form on each page of a report directed to a printer or a file. This is equivalent to use of the OVERLAY option of the SETPTR command except that it applies only to the one report.

 

The subr.name qualifier is the name of a catalogued subroutine that will emit the page overlay. This subroutine takes a single argument, the print unit number, and should not perform any other action.

 

 

Example

 

LIST ORDERS OVERLAY ORD.OV LPTR

 

This command lists the ORDERS file, overlaying each page with a graphical image generated by the ORD.OV subroutine.
