How to execute DOS command from an Ada program ?

Hi,

I am using Ada95 to develop a tool which will execute/call a DOS batch file.
Anyone knows how ? Thanks

If you use GNAT you may take a look at GNAT.OS_Lib and the Spawn
procedure/function there. For executing a batch file you may also need
Getenv to retrieve the name of the command processor (environment
variable COMSPEC) to let it execute the batch.

Much thanks for your support, Vinzent.

That obviously depends on the OS you are on (Mac, Unix?)
Therefore it isn't part of the standard for all Ada compilers.
But it's very commonly needed.
So your compiler vendor surely has supplied some library functions to do it.
Remember that Ada is not limited to MS Windows systems.

Since you are using GNAT you might want to take a look at:
