External Subroutine

Hi,
Where would we prefer using external subroutine over subprogram.
Thanks
Abhishek

An external subroutine can share a GDA with the calling routine, unlike a subprogram, which requires an explicit field list to pass parameters.

Please don’t use external subroutines, they are just not worth the effort and they come with some big problems

Well, at least in theory EVERYTHING may be written within ONE HUGE PROGRAM which would be “VERY-VERY EFFICIENT”
This is my 2 cents.
By the way, our shop uses NATURAL (with External Subroutine as well) for many-many years, and it looks like there`s nothing wrong with them (by “them” I mean our company, NATURAL and External Subroutines themselves
