ID 21501

There are pending invalid control blocks at main program end.

Description

In a main program, an invalid control block statement (e.g. $IF-$ENDIF) was not closed, i.e. an assigned $ENDIF is missing.

Invalid in this context means that the programmed condition is false, and the NC blocks in this branch are not executed.

Example:

Wrong:

% main

N10   G00 X0 Y0 Z0

N20   P1=0

N30   $IF P1 == 1

N40     Y100

N100    X100

N150 M30 ← $ENDIF of $IF P1.. missing.

Correct:

% main

N10   G00 X0 Y0 Z0

N20   P1=0

N30   $IF P1 == 1

N40     Y100

N100    X100

N105  $ENDIF ← Invalid $IF is ended

N150  M30
