The GDELETE subroutine is a graphical call that searches the current catalog and deletes the first segment found with the name segment-name. This call is part of the traditional graphics subsystem, which is no longer being developed.

An example of a valid statement follows:

/* SEG_A is defined as a character matrix        */
/* that contains the name of the segment to delete */
call gdelete(seg_a);

The segment can also be specified as a quoted literal, as follows:

call delete("plot_13");
