How and why to use the ICU for programming

GDDM-PGF V2R1.3 Interactive Chart Utility
SC33-0328-01

As well as calling the ICU as a stand-alone utility, you can also call it from an application program you have written. This can let you do the following things that you cannot do when you use the ICU in the standard way:

Printing overnight or at non-peak times.
Restricting access of charts to only some users.
Controlling the access for users in other ways and generally tailoring the ICU.
Running the ICU to produce output for devices such as the 4250 printer.

Details are in the GDDM-PGF Programming Reference book, and in the GDDM Base Application Programming Guide book, see "GDDM publications" in topic I.2.
