Macro Call via G Function

Analogous to G65, a macro can be called up via a G number.
50 G function replacements ca be configured by means of the machine data
$MN_EXTERN_G_NO_MAC_CYCLE and
$MN_EXTERN_G_NO_MAC_CYCLE_NAME.
The address A--F, H--K, M and P--Z can be use as the parameter. Only the integer
value can be used for the address P and L. Address L is for the number of repition.
Please refer to the chapter 4.10.2 "Macroprogram call (G65, G66, G67)" for the
parameter programmed in the block.
The number of the programmed G macro is stored in the variable $C_G. All further
G functions programmed in the block are treated like ordinary G functions and per-
formed before the execution of macro program. The programming sequence of the
addresses and G functions in the block is not fixed and does not influence the func-
tionality.
Restrictions
S The G function replacement can be execute in ISO mode (G290).
S The address O with G function replacement is signaled with an alarm.
S One single G/M function replacement (or generally only one subroutine call) can
be executed per parts program line. Conflicts with other subroutine calls, e.g.
when a modal subroutine call is active, are signaled with alarm 12722.
S The G function replacement with end of subprogram (M99) or end of program
(M02, M30) is denied by the alarm.
S If a G macro is active, no other G/M macro or M subroutine is called up. In this
case, M macros/subroutines are executed as M functions. G macros are execu-
ted as G function, if a corresponding G function exists; otherwise, alarm 12470
"G function unknown" is output.
S In all other respects, the same restriction as for G65 are valid.
Configuration examples
Call of the MAKRO_G21 subroutine by the G21 function as well as G123.
$MN_EXTERN_G_NO_MAC_CYCLE[0] = 21
$MN_EXTERN_G_NO_MAC_CYCLE_NAME[0] = "MAKRO_G21"
$MN_EXTERN_G_NO_MAC_CYCLE[1] = 123
$MN_EXTERN_G_NO_MAC_CYCLE_NAME[1] = "MAKRO_G123"
$MN_EXTERN_G_NO_MAC_CYCLE[2] = 421
$MN_EXTERN_G_NO_MAC_CYCLE_NAME[2] = "MAKRO_G123"
