Eight-digit program number (M98, G65/G66)

An eight-digit program number selection is activated with the machine data 20734 $MC_EXTERN_FUNCTION_MASK, Bit
6=1. This function affects M98 and G65/66.
y: Number of program runs
x: Program number
Subprogram call
$MC_EXTERN_FUNCTION_MASK, Bit 6 = 0
M98 Pyyyyxxxx or
M98 Pxxxx Lyyyy
Max. four-digit program number
Addition of program number always to 4 digits with 0
Example:
M98 P20012: calls 0012.mpf 2 flows
M98 P123 L2: calls 0123.mpf 2 flows
$MC_EXTERN_FUNCTION_MASK, Bit 6 = 1
M98 Pxxxxxxxx Lyyyy
There is no extension with 0, even if the program number has less than 4 digits.
The programming of number of passes and program number in P(Pyyyyxxxxx) is not possible, the number of passes must
always be programmed with L!
Example:
M98 P123: calls 123.mpf 1 Pass
M98 P20012: calls 20012.mpf 1 Pass
Caution: This is no longer compatible with ISO dialect original
M98 P12345 L2: calls 12345.mpf 2 Passes
Modal and blockwise Macro G65/G66
$MC_EXTERN_FUNCTION_MASK, Bit 6 = 0
G65 Pxxxx Lyyyy
Addition of program number to 4 digits with 0. Program number with more than 4 digits leads to an alarm.
$MC_EXTERN_FUNCTION_MASK, Bit 6 = 1
G65 Pxxxx Lyyyy
There is no extension with 0, even if the program number has less than 4 digits. A program number with more than 8 digits
leads to an alarm.

Polar coordinates (G15, G16)

While programming in polar coordinates, the positions in the coordinate system are defined with a radius and/or angle. Polar
coordinate programming is selected with G16. It is deselected again with G15. The first axis of the plane is interpreted as
polar radius, the second axis as polar angle.
