Any Desired Program As Subprogram - HEIDENHAIN TNC 320 User Manual

Any desired program as subprogram

Operating sequence
If you want to program variable program calls in
connection with string parameters, use the SEL
PGM function.
1 The TNC executes the part program up to the block in which
another program is called with CALL PGM.
2 Then the other program is run from beginning to end.
3 The TNC then resumes the first part program (i.e. the calling
program) with the 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
