ID 21500

There are pending invalid control blocks at local subroutine end.

Description

In a local subroutine, 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:

%L sub1

N10   G00 X0 Y0 Z0

N20   P1=0

N30   $IF P1 == 1

N40     Y100

N100    X100

N110  M29  ← $ENDIF of $IF P1.. is missing.

%main

N010 X0 Y0 Z0

N020 LL sub1

:

N1000 M30

Correct:

%L sub1

N10   G00 X0 Y0 Z0

N20   P1=0

N30   $IF P1 == 1

N40     Y100

N100    X100

N105  $ENDIF ← Invalid $IF is terminated

N110  M29  

% main

N010 X0 Y0 Z0

N020 LL sub1

:

N1000 M30
