Hi to all,

After having had a nice conversation with JimB (Re: Public variables Thread #667392 Message #668939) I'd like to propose to the community to use g as scope indicator for variables that are declared public OR PRIVATE in the MAIN program. The g then indicates that it are GLOBAL variables. Global (g) is then simply an indicator that they're visible to the entire application. Here's an example of a main program.

*	Declare GLOBAL variables. Notice that I use the g here for PRIVATE variables. 
*	The g indicates that these variables are visible/global to the entire application.
*	The only place where private variables are allowed to start with a g is in the main program.
*	This usage of g is different from what's proposed in the vfp-documentation (where it's 
*	advised for public variables).
private goMainWindow, goNewActivity, goReports, goOptions

*	References to forms.
store null to goMainWindow, goNewActivity, goReports, goOptions

do form MainWindow name goMainWindow

read events

release all like g*
*	The ALL LIKE wouldn't work for public variables.
*	However, it's not even a necessary statement, for these variables 
*	will go out of scope anyway on return.

RETURN

Feedback please.
