4.4 Model Customization
Virtual Machine Reference, Model Customization
This section describes the model customization features available with QUEST.
� Virtual Machine uses the ICAM Macro Language facility (described starting on page
123) to customize models. This is the same programming facility used with CERUN and
GENER.
� The Startup macro and Shutdown macro (on page 145) allow you to customize the actions
of the model at the start and end of processing.
� Event macros (on page 146) provide customization control at other key events in the
simulation of the program.
� The Dialog Editor (on page 148) allows you to build custom dialog boxes, which can be
activated during processing to query the NC programmer for any necessary information.
� Many built-in Virtual Machine specific macro functions (on page 147) are available to
control model behavior.
� There are also a couple of Virtual Machine specific macro variables (on page 194) that
may prove useful.
Syntax Conventions
The syntax for the macro language is listed using the following format:
� Square brackets [ ] encase syntax that is optional. The ~ symbol preceding the item, as in
~[,a], indicates that the item can be repeated zero or more times.
� Parentheses ( ) encase syntax that lists a number of choices, one of which is required. The
~ symbol preceding the item, as in ~(,a), indicates that the item can be repeated one or
more times. The parentheses are omitted when the syntax is a simple choice among a
number of keywords.
� Any value not contained in square brackets or parentheses must be programmed each
time the command is used.
� Formal keywords will be shown in upper case, as in ON and WHILE.
� Lower case italicized words identify requirements for numeric values, as in label_name
or value.
� Alternate forms for a command will be listed separately, with the command name repeated.
