Boundary conditions

3.1

Function-specific boundary conditions

3.1.1

Within subroutines

Meaning
Clear retrace support within subroutines depends on whether the subroutine call is made
outside or inside a program loop.
Outside
Clear retrace support is possible if a subroutine is called outside a program loop.
Inside
Clear retrace support may not be possible if a subroutine is called inside a program loop.
See Subsection "Boundary conditions / Function-specific boundary conditions / Within
program loops".
Number of passes P
Subroutine repetitions using number of passes P are taken into account for retrace support.
This means that retrace support is performed in the part program with the correct reference
to the part program block and number of passes P to the program continuation point of the
contour.
