ENDPROC

Ends execution of the current procedure (defined with DEF PROCname) and returns to the caller.
Execution resumes at the statement after the PROCname(...) call.

Example: simple procedure

DEF PROCgreet
    PRINT "Hello from a procedure!"
ENDPROC
 
PROCgreet

Example: conditional early return

DEF PROCprint_if_positive(N)
    IF N <= 0 THEN
        ENDPROC
    ENDIF
 
    PRINT "Value = "; N
ENDPROC
 
PROCprint_if_positive(5)
PROCprint_if_positive(0)

Rules & behaviour

ENDPROC must appear inside a procedure body started with DEF PROCname.
Using ENDPROC outside a procedure is an error.
Functions (DEF FNname) do not use ENDPROC; a function returns with a final line that begins with =.

Loop scope

Loops (FOR, WHILE, REPEAT) are scoped to the current procedure.

Any active loops created inside a PROC are discarded when ENDPROC is reached unless they have already been exited normally.

If execution continues and a loop-closing statement is encountered with no matching loop, a runtime error is raised (e.g. NEXT without FOR).
