Parameter #1 is set at 1.1 in macro 1001.
X Axis is moved 1 unit and then macro 1001 is called and
executed 2 times.
Z Axis is moved .25 units and then macro 1001 is called and
executed 2 times.
Parameter #1 is set at 2. in macro 1002
.
X axis is moved 1 unit then macro 1002 is called and
executed once.
Macro 1002 is canceled.
Macro 1001 is canceled.

Parameter #1 for macro 1001 is set at 1.7.
Macro end.

Z Axis moves an amount equal to the current value set
parameter #1 (in this case always 2 units). Macro 1001 is
called and executed twice.
Macro end.
Important: When the control executes block N040, the original value as
set in block N020 for parameter number 1 is ignored, and the most current
value (1.7) is used. The first time macro 1001 is executed, Z moves 1.1
units. The second time macro 1001 is executed, Z moves 1.7 units.
Use this format when calling a paramacro using the G66.1 command:
G66.1 P_ L_ A_ B_;
Where: Determines:
P the program number of the called macro. P ranges from 1 - 99999.
L the number of times the macro is executed. L ranges from 1 - 9999, and can be
expressed as any valid parametric expression. If not specified, the control uses a
default value of 1.
A-Z Optional argument statements. May be programmed using any letter from A to Z
excluding G, L, N, O, or P. Used to assign numeric values to parameters in the
paramacro. Arguments may be specified as any valid parametric expression.
