Setting and Passing Parameters
You can set parameters for a macro before the sub-program call
(M98 Pn). Refer to Example 1. Blocks 10 to 12 define variable values
for the sub-program called in Block 13.
It may be more convenient to use macro call G65 Pn or G66 Pn to
pass variables to the sub-program by letter address. This is how a
canned cycle operates. Refer to Example 2. Values are passed on for
parameters A, B and C.
Macro call G65 Pn contains a loop option (Ln). Where, n is the
number of repetitions of the sub-program called.
Macro 1 is called three times (Ln equals 3).
When parameters are passed to a macro body by letter address, the
contents of the parameters are stored in local variables.
Letter Addresses:
Example 1:
N10
#151 = 2
N11
#151 = 3
N12
#151 = 3.4
