12.2. CALLING IN A STANDARD SUBROUTINE
A standard subroutine may be called in from any program or other subroutine (standard
or parametric). Calling in a standard subroutine is achieved by function G20. The structure
of a call block is:
N4 G20 N2.2
N4 : Block number
G20 : Subroutine call
N2.2 : The two figures to the left of the decimal point identify the number of the
subroutine called in (00-99).
The two figures on the right of the decimal point indicate the number of times the
subroutine is to be repeated (00-99). Unless it is programmed by a parameter, in which case
the limits are 0 and 255. However, when no number is indicated, the subroutine will be
executed only once. No other additional information can be programmed in the block
calling in a standard subroutine.
12.3. PARAMETRIC SUBROUTINES
It is basically similar to an standard subroutine except for the fact that values can be
assigned to up to 15 parameters in the call block (G21).
When the execution of the parametric subroutine is finished (G24), the values assigned to
the parameters in the call block are recovered even though different values might be
allocated to them during the subroutine.
