Running other apps

[Ianmac]

Hi.
I have written an app which, like topsy, just grew and is now around 1000 lines of code.
I now want to expand this further, but rather than deal with an exponentially increasing number of if - then, case or other option statements, it strikes me it would be easier to copy the original app and adapt it for each of the various cases that I want it to tackle and have a single front end app which, on clicking a button would open the appropriate app to do that single task and on closing that app it would start the front end again.
Is there a specific piece of coding to do this or am I now entering the realms of .dll's ?
Any help would be appreciated.

Hi Ianmac,
I have similar project as yours, it became huge file and takes time to open. Since other application modules need not to open everytime by the user, I have broke it up to several apps. I use 'shell' to open them in background. Some of my apps still takes time to open. It will be faster once Basic4ppc version 6 is released.

See this thread for reference...
Getting value from other other application in runtime

We could ask other members what other method could be done.

Many thanks for the reply, Shell was exactly what was required. I had looked through all the options I could think of from other programming languages but missed that one, all I have to do now is duplicate and amend the original.
