Hi, Ria!

A set of public variables are defined in A.exe . They are assigned values from
an INI file. These variables are used in the program to define the location
of data etc.

To store such information it's always better to use properties on an object instead of a lot of public variables:
- Create an object called goApp
- Add all properties you need and fill them.
- At all places you have to refer to any properties use goApp.MyProp...

NOTE: To bring that to live "goApp" itself must be a public variable, but the one and only in your system.


Now to the problem with A.EXE and B.EXE - here is my idea according to my solution above:

...
LOCAL loApp
* store goApp to a safe place
loApp = goApp
* release goApp
RELEASE goApp
* call the EXE
DO b.EXE
* redefine goApp
PUBLIC goApp
goApp = loApp
