What are Action Logic Functions?

Functions provide you with critical system information at any given time during the simulation. They can be used in an assignment statement to set the value of a variable or attribute or in an IF…THEN statement to make a decision based on system information. There are several system functions:

• Clock()
• Contents()
• FreeCap()
• FreeUnits()
• GroupQty()
• OwnedResource()
• Percent()
• ResQty()

 System reserved words cannot be used as variable names, attributes, or scenario parameters.
