Statements

A statement is a command in action logic that does something and sits on its own line: assign a value, seize a resource, set a time, branch, or route an entity. This section is the reference for every statement, grouped by what it does:

Assigning values: SET, INC, DEC, and local variables.
Timing: TIME and WAIT UNTIL.
Flow control: IF, WHILE, FOR, and jumps.
Resources in logic: GET, FREE, USE.
Creating and naming entities: CREATE, NEWNAME.
Display: DISPLAY, DEBUG.
Signals, gates, and other logic: signals, gate control, and calling other logic.
Inventory: STORE, TAKE, REQUEST.

For where and how you type these, see Action Logic. For the value-returning calls you use inside them, see Functions.

What changed in version 7

A few older statements have been replaced:

A timed pause is now TIME 5 min, not WAIT 5 min or PROCESS TIME.
A direct assignment is v_X = 5 (or SET v_X TO 5); the old ASSIGN keyword is gone.
To seize several resources at once, use GET … AND … in place of JOINTLYGET.

LegacyHow this worked in the previous version

Statements are simply commands to be executed at particular stages in an entity’s progress through the process. The following pages explain in detail each statement listed below.

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