SYSTEMQQ

Portability Function: Executes a system command by passing a command string to the operating system's command interpreter.

Module

USE IFPORT

result = SYSTEMQQ (commandline)

commandline

(Input) Character*(*). Command to be passed to the operating system.

Results

The result type is LOGICAL(4). The result is .TRUE. if successful; otherwise, .FALSE..

The SYSTEMQQ function lets you pass operating-system commands as well as programs. SYSTEMQQ refers to the COMSPEC and PATH environment variables that locate the command interpreter file (usually named COMMAND.COM).

On Windows* systems, the calling process waits until the command terminates. To insure compatibility and consistent behavior, an image can be invoked directly by using the Windows API CreateProcess( ) in your Fortran code.

If the function fails, call GETLASTERRORQQ to determine the reason. One of the following errors can be returned:

The command line character limit for the SYSTEMQQ function is the same limit that your operating system command interpreter accepts.

Example

 USE IFPORT
 LOGICAL(4) result
 result = SYSTEMQQ('copy c:\bin\fmath.dat &
                         c:\dat\fmath2.dat')
