BREAK and CONTINUE

The BREAK and CONTINUE verbs alter the program execution sequence. BREAK terminates the currently active LOOP/REPEAT, even if there are several levels of active IF/ENDIF instructions. CONTINUE forces execution to resume at the currently active LOOP instruction even if there are several levels of IF/ENDIF instructions. These structures use the following formats:

(1)	[label]	BREAK
(2)	[label]	BREAK	IF [NOT] {condition}
(3)	[label]	CONTINUE
(4)	[label]	CONTINUE	IF [NOT] {condition}

Where:

label

Optional. A Program Execution Label.

condition

Required. A valid check for a Flag or Expression.

Flags Affected: Function Key Flag

Note the following:

The Function Flag is reset if tested and it was true.
If a FILEPI instruction is active, the FILEPI count is not decremented by this instruction.
BREAK and CONTINUE statements must be physically located within the scope of a LOOP/REPEAT structure.

Example 1:

A	FORM	2
	LOOP
	KEYIN	*N,"ENTER A: ",A;
	BREAK	IF F1
	DISPLAY	*N,"VALUE: ",A;
	REPEAT

The LOOP is terminated when the F1 function flag is TRUE.

Example 2:

A	FORM	2
	LOOP
	KEYIN	*N,"ENTER A: ",A;
	BREAK	IF F1
	CONTINUE	IF (A=5)
	DISPLAY	*N,"VALUE: ",A;
	REPEAT

The CONTINUE causes the program execution to branch back to the LOOP if the operator entered '5' into 'A'.
