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.

Example 1:	N10	#151 = 2
	N11	#151 = 3
	N12	#151 = 3.4
	N13	M98 P1
	N14	-----

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.

Example 2:	N20	G65 P1 A2 B3 C3.4
	N21	-----

Macro call G65 Pn contains a loop option (Ln). Where, n is the number of repetitions of the sub-program called.

N20	G65 P1 A2 B3 C3.4 L3
N21	-----

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:

A = #1	B = #2	C = #3	D = #7	E= #8	F = #9
H = #11	I = #4	J = #5	K = #6	M = #13	Q = #17
R = #18	S = #19	T = #20	U = #21	V = #22	W = #23
X = #24	Y = #25	Z = #26
