How to start another application within an ADA program?

How to start another application within an ADA program?

[tolkamp]

Is it possible to start an other apllication (eg Microsoft Word) within an ADA program? If so, how do I do it?

I tried to select the executable file with the JEWL File-Browser, but this did not work.

I don't think there's anything for this in the standard library.

If you're using Gnat, look at the Spawn and Non_Blocking_Spawn functions in Gnat.OS_Lib.

Yes.

Look at this thread (you can also look for "system_call").

Yes.  (And Ada is not an acronym.)

1. You can use whatever system calls available. E.g. UNIX's system/exec* or
Windows' CreateProcess. For the latter use Win32 bindings available with
GNAT.

2. A portable way to do it is, already mentioned, GNAT's OS library, or GTK
(Glib). Here is the bindings:

You can feed the spawned process' input and catch its output directly or
using GTK's text buffers.

I believe that Qt also has some means to spawn processes.

As a complement to other answers, perhaps you want to start an application exactly like Windows does when you do Window-key-R or "start [something]" from the command line cmd.exe. For instance "start winword" will start MS Word (even though winword.exe is not in the path), and "start mydoc.doc" will start MS Word and open mydoc.doc as well in it.
In that case, look for "Start" in

Another option is the GNATCOLL.Scripts package:

I know it's not exactly what you're asking for, but it does provide a
method to start an external proces.
