Calling Subroutines from a Main Program
As of now it is possible to call subroutines (with file extension.simpl) from a main program. This
function is useful, for example, if several programs are to be processed one after the other. Up to
now this was only possible with external SimPL sequences (file extension.seq).
During processing, the main program of the external module is executed, including all subroutines
and embedded sequences called by it. To do this, the subroutine must first be specified in the
header of the module to be called via a user module declaration.
