Paramacros
Chapter 28
28-51
Precautions must be taken when attempting to nest AMP assigned macro
calls since many combinations of these calls may not be valid. The system
installer determines in AMP the functionality of the AMP-defined macro
call when nested. These two options are available (see the system
installer’s documentation to determine which applies to your system):
Works as a macro call -- When “works as a macro call” is selected, G--,
M--, T--, S--, or B--code macro calls that are nested and called by other
G--, M--, T--, S--, or B--code macro calls allow nesting as shown in
NO TAG.
Table 28.I
Works as a Macro Call
CALLING PROGRAM TYPE OF MACRO NESTED 1

G66,or
G66.1 AMP-G AMP-M
AMP-T
S or B
G65, G66 or G66.1 Yes Yes Yes Yes
AMP G-code Yes No Yes Yes
AMP M-code Yes Yes No No
AMP-T--, S--, or B--code Yes yes No No
1 What Yes/No means:
Yes ---- the macro type across the top row may be called from the macro type down the left column.
No ---- the macro type across the top row may not be called from the macro type down the left column.
When this nesting is attempted, the control will execute any other operation that would normally be
performed by that G--, M--,T--, S--, or B--code (as defined by the system as a standard code, PAL, or
some other AMP feature) and the paramacro call normally made by that code is not performed.
Works as the system-defined code -- When “works as the system
defined code” is selected, G--, M--, T--, S--, or B--code macro calls that
are nested and called by other G--, M--, T--, S--, or B--code macro calls
allow nesting as shown in NO TAG.
