Statement NEXT

Advance and test the innermost active FOR loop.

Syntax

NEXT variable

Parameters

Parameter	Meaning
`variable`	Must match the top FOR frame.

Behavior

Adds the saved step. If the signed loop bound is still satisfied, resumes the loop body; otherwise pops the frame. A mismatched variable or wrong frame type is status 36.

After normal termination the variable contains its incremented value, typically one step beyond the bound. A signed-overflow exit retains the wrapped bit pattern.

Example

10 FOR I=1 TO 3
20 PRINT I
30 NEXT I
40 PRINT I

Limits and diagnostics

The variable is mandatory. NEXT I,J and an unnamed NEXT are not supported.
