Stephane,

I haven't tried it myself, but is the _VFP.LanguageOptions feature (new in VFP7) of any help in this?


>You may be right, it's possible no other language has this feature. My suggestion is to have a SYS() option, but an option like Option Explicit would do the trick as well.

>>>New SYS() Function to specify the scoop of undeclared variabled

>>>Currently when using an undeclared variable, VFP creates the new variable whith a private scoop creating potential problem in MTDLL. Having a new SYS() Function to modify the default behavior so VFP creates all un-Explicitly declared variables with a LOCAL scoop would greatly improve Com servers stability.

>>>I fixed the loCusror to loCursor and the C5 went away. This kind of problem is very difficult to find especially when you have hundreds of programs being modify by many developers.
