NAME

replace - overwrite existing display list commands with new ones

SYNOPSIS

C
replace(t, offst)
Tag t;
Offset offst;

FORTRAN
subroutine replac(t, offst)
integer t, offst

Pascal
procedure replace(t: Tag; offst: Offset);

DESCRIPTION

Replace combines the functions of insert and delete.  It takes two arguments, a tag t and an offset offst.  Graphics commands that follow replace overwrite existing commands until a closeobj, insert, delete, or replace command terminates the replacement. Replace requires the new command to be the same length as the one it replaces, which makes replacement operations fast.  More general replacement can be done with the delete and insert commands.  Replace is meant as a quick means of replacing a command with a version of itself containing different arguments. 

SEE ALSO

closeobj, delete, editobj, insert

NOTE

This command can only be used in immediate mode.
