Descriptions of the Library Routines 2SYSTEMQQPortability Function: Executes a system command by passing a command string to the operatingsystem’s command interpreter.Module: USE IFPORTSyntaxresult = 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 commandinterpreter file (usually named COMMAND.COM).On Windows* systems, the calling process waits until the command terminates. To insurecompatibility 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 followingerrors can be returned:• ERR$2BIG – The argument list exceeds 128 bytes, or the space required for the environmentformation exceeds 32K.• ERR$NOINT – The command interpreter cannot be found.• ERR$NOEXEC – The command interpreter file has an invalid format and is not executable.• ERR$NOMEM – Not enough memory is available to execute the command; or the availablememory has been corrupted; or an invalid block exists, indicating that the process making thecall was not allocated properly.The command line character limit for the SYSTEMQQ function is the same limit that youroperating system command interpreter accepts.CompatibilityCONSOLE STANDARD GRAPHICS QUICKWIN GRAPHICS WINDOWS DLL LIBSee Also: “SYSTEM”ExampleUSE IFPORTLOGICAL(4) result2-479
