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.. is 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
