External subroutine with parameter doen't work

Hi,
i got this problem.

main program:

G90 G0 X0
O<posi> call [20]
M02


file posi (external soubroutine):
O<posi> sub
G0 X#1
G0 X100
O<posi> endsub
M02


The main program call the subroutine, the X axis move to 100 but doen't move before to 20.
I think that the external subroutine doesn't read the parameter. Is there a mistake?
any suggestions?

Thanks

Thanks, you are right! I didn't see the stop because the two point are on the same line. I changed axis movement and all work fine.

Another question, can i see in a external soubroutine a global variable?

example:

main program:

G90 G0 X0
#102=1000
O<posi> call [20]
M02


file posi (external soubroutine):
O<posi> sub
G0 X#1
G0 Y100
G0 Y#102
O<posi> endsub
M02

Thanks.

Hi,
in this moment i am understanding the origin of all my problems!!!!!!

At the biginning I created a file named "posi" for my external soubroutine and the O<posi> call had a problem to open the file because it search for "posi.ngc".
After this i created "posi.ngc" and all worked fine. In a second moment i modified "posi" file instead "posi.ngc" and this confused me.

The right call for an external sabroutine is:

o<FILE_NAME> call

This istruction search the file on hard disk path named "FILE_NAME.ngc"

It works also with global variable.

Tested on EMC 2.4.6

Thanks.

Yes

However, to do so violates all the principles behind object oriented programming, that give rise to the use of discrete subroutines in the first place.

This may sound pedantic, but there is good logic behind it.

A subroutine should not be reliant on any external data, just the parameters passed when it is called.
That way if you find a far better way of implementing the moves in the subroutine, you can rewrite it and so long as the parameter interface is the same, it will continue to work with all the code which previously used it.

If you use a global variable then you might just as well write the whole lot in-line and dispense with the separate file.

The subroutine you wrote will not work unless each piece of code you use it with, has the same global declaration

So what you should do is just pass as a parameter

O<posi> call [20] [1000]
