You can directly read or set global variables in your mapbasic program
(provided they are not global arrays). First you need to defined a Mapbasic
application object, the you can or set variables from it
Dim objMB as object
set objMB = MI.MBApplications("mbprog.mbx")
Then:
VBVariable = objMB.MBGlobals("MbVariable").Value
or
objMB.MBGlobals("MbVariable").Value = VBVariable
VBVariable is a variable in VB
MbVariable is the name of a global variable in mapbasic program mbprog.mbx.
