CISSUE@

Platform

x64, Win32

Purpose

To issue a system command.

Syntax

SUBROUTINE CISSUE@(A,IFAIL)
CHARACTER (LEN=*) A
INTEGER (KIND=2) IFAIL

Description

Issues the command stored as a character string in A. IFAIL is returned as one of the following:

 

IFAIL

Meaning

 

0

Successful invocation of a command processor to execute the command

 

1

A command processor could not be invoked

Notes

This is a Silverfrost library function.
The value of IFAIL refers to the success or failure of invoking the MS-DOS command processor COMMAND.COM. Unfortunately, MS-DOS does not provide a mechanism whereby the success or failure of the invocation of the particular command can be reported back to the caller. So, for example, if you get a system error such as "Not found" for the command, IFAIL will be returned as zero.

 

The use of CISSUE@ to start TSR programs should be avoided since this can fragment memory.
