RUNNING PROGRAMS
CRIMSON USER MANUAL - MODULAR CONTROLLER
such that an example such as Data.1:=(Level>10) can be used to set or clear a bit
depending on whether or not a tank level exceeds a preset value.
RUNNING PROGRAMS
Programs may be invoked within actions by following the program name with a pair of
parentheses. For example, Program1() will invoke the associated program. The program will
execute in the foreground or background as defined by the program’s properties.
USING FUNCTIONS
Crimson provides a number of predefined functions that can be used to perform various
operations. These functions are defined in detail in the Function Reference. They are invoked
using a syntax similar to that for programs, with any arguments to the function being enclosed
within the parentheses. For example, SetLanguage(1) will set the Master language to 1.
OPERATOR PRIORITY
All assignment operators fall into Group 14. In other words, they will be evaluated after all
other operators in an action. They are also unique in that they group right-to-left. This means
that code such as Tag1:=Tag2:=Tag3:=0 can be used to clear all three tags at once.
NOTES FOR EDICT USERS
Users of Red Lion’s Edict-97 software should note…
• The = operator can now be used instead of the := operator.
