Subprogram call (M98)
S M98 P xxxx yyyy
y: Program number (max. 4 digits)
x: Number of repetitions (max. 4 digits)
S The program syntax M98 Pxxxxyyyy is used to call a subprogram with the num-
ber yyyy and repeat it xxxx times. If the xxxx is not programmed, the sub--pro-
gram is executed only once. The subprogram name always consists of 4 digits
or is extended to 4 digits by adding 0's.
For example, if M98 P21 is programmed, the part program memory is searched
for program name 0021.spf and the subprogram is executed once. To execute
the subprogram 3 times, program M98 P30021.
S As an alternative, the number of subprogram executions can also be pro--gram-
med at address 'L'. The number of the subprogram is still programmed as
Pxxxx. If the number of executions is programmed at both addresses, the num-
ber of executions programmed at address 'L' is valid. A valid range for address
'L' is 1 to 9999.
S Nesting of subprograms is possible - the allowable nesting level is four. If the
nesting level exceeds this limit, an alarm occurs.
Example:
N20 M98 P20123 ;
N40 M98 P55 L4 ;
N60 M98 P30077 L2 ;
