Below is code in a VFP app that also runs in FPD26. The FPD26 version runs a screen and the VFP version runs a form:

#IF !'VISUAL' $ UPPER(VERSION())
	DO co_prnt.spr
#ELSE
	DO FORM co_prnt.scx NAME oco_prnt LINKED
#ENDIF		

One of my coworkers modified it to now be the below code:

#IF !'VISUAL' $ UPPER(VERSION())
	DO co_prnt.spr
#ELSE
	EXTERNAL PROC co_prnt.scx
	SET KEYCOMP TO DOS
	DO FORM co_prnt.scx NAME oco_prnt LINKED
	SET KEYCOMP TO WINDOWS
#ENDIF		

My question is why add the EXTERNAL PROC line? Isn't that NOT necessary in VFP? All functions running in the vfp8 form are contained in the form itself as properties of the form. I could understand a EXTERNAL FORM command if I was using macro substitution, but I'm not.

TIA,
