moving my subs

[s0l0seven]

hello guys.

i was wondering what would be involved in altering my post to move my subs to the begining of my generated code. like before the program No.

It's a tad complicated, but here are a few points to rough out the solution for you.

You would need to send the main NC code out to an external file using the 'subout' variable:

extprg = yes

subout = 3

Also every time subout = zero appears in the post, would need to be changed to subout = 3

You may also need to override the tendency of the post to return to subout = zero automatically after subs.

At the peof end of file postblock you would need to change back to subout = 0, then merge and clear your subs first, then the main file afterwards:

code:

---

n, "M30", e

subout = zero

mergesub

clearsub

mergeaux

clearaux

mergeext

clearext

"%", e

---

The Post manual has more info on the variables, and your dealer may offer post customization services.

Dave is correct, it can be a little complicated if your goal is to change the format of the subprogram output instead of just moving them to the top of the program. For example an inline subroutine method used in the Fadal's would require much more modifications.

The predefined variable sub_level can be set to 2 which will cause the main program level to be written to the EXT file instead of the NC file so you don't need to set subout and extprg as Dave mentioned. However you still need to modify the PEOF postblock as he described to build the NC file back in thew correct order.
