Synchronous SCALL versus asynchronous SCALL
Under Visual PRO/5 you have your choice of a synchronous SCALL (the Visual PRO/5 program stops running until the system call returns), or an asynchronous SCALL (the Visual PRO/5 program continues, and can even exit before the SCALL finishes). The way to get an asynchronous SCALL is to add an ampersand (&) to the end of the command string. Without the trailing ampersand, you'll get a synchronous SCALL.
Example of a synchronous SCALL:
