This question would be easy to answer if we knew what language and
compiler you are using. Kind of hard to say otherwise.
In general, a global variable is declared outside of and prior to any
function that uses it. If you are using C and all of your functions
are in one file, for example, then here is how to do it:
// near the top of your file
static Char aString[30];
static Boolean OneFormHandleEvent( EventPtr eventP )
{
Boolean handled = false;
FormPtr frmP = FrmGetFormPtr( OneForm );
switch( eventP->eType )
{
case frmOpenEvent:
MainFormInit( frmP );
FrmDrawForm( frmP );
StrCopy(aString, "some string"); // save something in aString
handled = true;
break;
// other cases, etc.
default:
break;
}
return handled;
}
static Boolean TwoFormHandleEvent( EventPtr eventP )
{
Boolean handled = false;
FormPtr frmP = FrmGetFormPtr( TwoForm );
switch( eventP->eType )
{
case frmOpenEvent:
MainFormInit( frmP );
FrmDrawForm( frmP );
WinDrawChars(aString, StrLen(aString), 10, 20); // use aString
handled = true;
break;
// other cases, etc.
default:
break;
}
return handled;
}
