Paramacros
Paramacros are similar to subprograms, with many added features. Use
paramacros to create custom cycles that may require complex
mathematical calculations, access to wheel offset, work coordinates, wheel
position data, and the ability to alter normal program execution. The major
topics covered in this chapter include:

Parametric Expressions 20-1
Transfer of Control Commands 20-7
Parameter Assignments 20-12
Assigning Parameter Values 20-39
Backing Up Parameter Values 20-47
Macro Call Commands 20-48
Macro Output Commands 20-59
All of these features are valid in any block within a main program,
subprogram, or paramacro program. Most are permitted in an MDI
program unless stated otherwise. The only restriction is that no other
program commands, except other paramacro commands, can exist in a
block that contains paramacro commands. Macro and non-macro
commands cannot exist in the same program block.
This section contains the following subsections:

Parametric Expressions as G-Codes 20-6
Parametric expressions are mathematical or logical expressions that are
evaluated in a paramacro. The following subsections cover the operators
and function commands available for use on the control. These operators
and function commands are valid in any block within a program,
subprogram, paramacro, or MDI program.
