c.
The maximum nesting level of macro program
is quadruple including G65 and G66 calls,
That
of subprograms is also quadruple but separately.
d.
If macro programs are specified via MDI
during automatic operation, the maximum nesting
level is restricted to quadruple. With subpro-
grams,
up to four levelS of nesting are permitted
in tape mode or memory mode, or separately in
MDI mode,
(3) Relationship with MDI Operation
a. MDI writing permits the macro call and the
execution of the called macro,
b. MDI writing does not permit or execute macro
body commands such as operational commands and
control commands.
c.
When a macro program being executed is
stopped by the single block stop function, any
MDI writing command not related to the macro
may be specified and executed.
(4) Relationship with Address Search
The address search function is not permitted to
search for the sequence numbers in the macro
body.
(5) Relationship with Single Block Switch
a. The operational command and control com-
mand blocks do not single–block stop if the
single block switch is turned on.
This switch
is enabled for the other macro program blocks.
b. However, when setting number #6004D1 = 1,
the single block switch is enabled for the opera–
tional command and control command.
c.
System variable #3003 (for the control of
single block stop see 2.8.23. 5) and setting #6004
Dl mentioned above operate as shown below:
L--
DI=O
=lor3
4
DI=O
=Oor2
Dl=l
I
=lor3
T
Dl=l
=Oor2
When Single Blcck
Switch is on
None of the operational
commands, control commands,
and general commands stoD,
Operational commands and
control command do not stop.
General ccfnmands stop.
None of the operational
command, control commands,
and general commands stop.
All of the operational
commands, control commands,
and general commands stop.
(6) Relationship with Optional Block Skip
The slash “/” character used in the right-hand
side of an operational expression or in brackets
is assumed to be the operator for quotient. It
does not mean the optional skip.
(7) Parameter Setting of Program Number
Classification
(1) Disabling of Program Registration, Erase,
And Edit
The following setting is permitted to protect the
registered user macros and subprograms from
inadvertent destruction:
Setting
Number
#6004
D2 =1...
The programs of program numbers
#8000 through #8999 are disabled for registra-
tion, erase, and edit.
D2 =0...
Registration, erase, and edit are
enabled.
Parameter
Number
#6021
D7 =1...
The programs of program numbers
#9000 through #9999 are disabled for registra-
tion, erase, and edit.
D7 =0..
. Registration, erase, and edit are
enabled.
(8) Effects of Reset Operation
a. A reset operation resets all local variables
(#l through #33) and part of common variables
( #100 through #149) to “blank. “
b, A reset operation resets the user-macro
multiple call state and the multiple DO loop state,
making the program pointer return to the pro-
gram head.
