There is no reason why your normal launch can't be written without globals so that it is the same as your sublaunch case. It will require a little extra effort though. Here's what I do to make a nice tight module that has no globals:
1.) Put all globals into a single structure (or several structures inside a single structure). 2.) Create an init function for that module (either called during AppStart or during a form open event). This function allocates a chunk of memory and then stuffs it into a feature. 3.) Now every time you enter that module (every external entry function), you simply get the feature pointer and then access the "globals". 4.) If other modules need to see these globals then you simple publish the feature number and structure so they can get it (or provide access functions in the module that allows retrieval and setting). 5.) Create a GetModuleGlobals function 6.) Create a DestroyGlobals function to be called during AppStop or during the form close processing. If you do all these things, then your normal launch doesn't use globals, and then any sublaunches can just use the same code and not worry about globals.

Ah, now I understand. Why do you need global variables? You could write a separat EventLoop which is used if you have to display this form and are called without globals. It will be lead to some double parts in your code, one for normal launch and one for beeing called without globals, but it would be the straightforward design. hope it helps, Henk (have a look in the example source from Palm, they do it alos for Find etc.) Abhijit Roy wrote: > Hi Henk, > > >>it's not the first time you come with this question. >> > > I know its not the first time I am putting this in > the forum .
