Documentation on all programming modes

m.fages

Hello everyone,
It is with great regret that I note that no answers have been formulated for my questions. The latter can be summed up in fact on request : Is there complete documentation concerning parametric programming, logic macro instructions, test, loop, call of subroutines, free #variables, etc...?
There is nothing of all that in the documentation of the DDCS V3.1 downloadable on Internet. The real question is : Is this possible, yes or no ? Yet subroutines like probe.nc or slib.nc use logical macro instructions, IF, (LT, GT, EQ...), WHILE, GOTOn etc... but this does not work for the user in the program main Gcode and subroutines in slib.nc ? Why is it so hard to get an answer ? I bought this cnc thinking of solving my machining projects and I find myself in a dead end.
Could someone answer me, the designer for example, thank you very much !!
Best regards
FM
