Chapter 9 PGL Commands
Ignore Commands (Normal, Create, and Execute)
Good parameters document what they are doing in different sections of their
code by including things such as Comment Fields or REM statements. In PGL
the same type of information can be included in PGL files by bracketing them
with the IGON and IGOFF commands.
In addition, some host systems pad the data stream with characters and
spaces before the SFCC. You can use these commands to cause the printer
to ignore these additional characters by inserting the IGON at the end of the
last PGL file and IGOFF at the beginning of the next PGL file. After sending
an IGON Command the printer will ignore ALL characters until it receives an
IGOFF Command. The commands that control the Ignore Mode are:
