Procedure
1 The TNC executes the part program up to the block in which
another program is called with CALL PGM

block after the program call
Programming notes
 No labels are needed to call any program as a subprogram
 The called program must not contain the miscellaneous functions
M2 or M30. If you have defined subprograms with labels in the
called program, you can then use M2 or M30 with the FN 9: IF +0
EQU +0 GOTO LBL 99
jump function to force a jump over this program
section
 The called program must not contain a CALL PGM call into the calling
program, otherwise an infinite loop will result
