G52 is being ignored by the sub program <self resolved>

[GDawson]

Good Morning,
I am trying to machine identical parts in a linear array with a subprogram using g52, something like this (ripped directly from pg 219 of the manual)
Example:
G0 X0 Y0 ; move to origin
M98 P9100 ; call subprogram
G52 Y4 ; shift coordinate system 4 inches in Y
G0 X0 Y0 ; move to new origin
M98 P9100 ; call subprogram again with new coordinates
G52 Y0 ; restore unshifted coordinate system

The G52 works and the machine moves to its new origin, then the sub opens, but it goes back to the original G54 location. there are no g codes other than movement in the sub (IE G0 G1,2,3)
It should work, what am I missing here?
Anyone else have issues with their sub program ignoring G52?
Thanks in advance
Greg

Figured it out, there were trash subs in the cncm program directory that centroid was preferring, ones with a .cnc file vs .nc. once all the trash was weeded out an the program was properly named (.cnc) it worked fine. Unlimited memory has been a learning curve around here, the 94 meldas m3 downstairs does not have the ability to store programs much past the ones you want, saves it from choosing the wrong sub.
