Sys(2450) -- What does it actually do?
I'm confused about Sys(2450).
I thought that VFP always searched the current executing module (FXP file) plus all "Set Procedure To" entities before looking to disk to find a function/procedure by a given name. i.e., so that if you had a FXP with multiple procedures in it, and one procedure in the FXP called another procedure PROC2 in the same FXP, then VFP would _always_ preferentially find PROC2 in the FXP and execute it, before looking for and executing a PROC2.FXP that might be on disk.
I also don't understand the scope of Sys(2450,1). Does this mean that VFP will search _all_ modules (FXPs) bundled into the APP or EXE to resolve a procedure/function reference before looking to disk... even search those FXPs that are not explicitly named in "Set Procedure To" statements?
