Indirectly programming G codes

Function
Indirect programming of G codes permits cycles to be effectively programmed.
Syntax
G[<group>]=<number>
Meaning
G[...]
<group>
<number>
Note
Generally, only G codes that do not determine the syntax can be indirectly programmed.
Only G function group 1 is possible from the G codes that determine the syntax.
The syntax-determining G codes of G function groups 2, 3 and 4 are not possible.
Note
Arithmetic functions are not permitted in the indirect G code programming. If it is necessary
to calculate the G code number, this must be done in a separate part program line before the
indirect G code programming.
64
: G command with extension (index)
: Index parameter: G function group
Type: INT
: Variable for the G code number
Type: INT or REAL
Comment
; Call the program, whose number is located in R10
(string cascading).
