EXECUTE Examples

Example 1:

	EXECUTE	"cmd /c del tfile.txt"	(MS-DOS)
	EXECUTE	"rm TFILE.TXT"	(Linux)

The program would be temporarily suspended while the file TFILE.TXT is deleted by the operating system. Normal screen I/O generated by this instruction would appear on the screen.

Note that since the "del" command is a part of the Windows shell, "cmd" must be loaded. The name of the command shell varies by operating system.

Example 2:

	EXECUTE	"cmd /c del tfile.txt > NUL"	(MS-DOS)
	EXECUTE	"rm TFILE.TXT > /dev/null"	(Linux)

The program would be temporarily suspended while the file TFILE.TXT is deleted by the operating system. However, normal screen I/O generated by this instruction would be redirected to the null system file and not appear on the screen or be stored in a file on disk.

Note that since the "del" command is a part of the Windows shell, "cmd" must be loaded. The name of the command shell varies by operating system.

Example 3:

	EXECUTE	"cmd /c dir . >dirfile.txt"	(MS-DOS)
	EXECUTE	"ls . > DIRECTRY"	(Linux)

The use of the greater than sign `>' tells the operating system that the screen I/O normally attributed to the instruction is redirected (not shown on the CRT) into the file `dirfile.txt'.

Note that since the "dir" command is a part of the Windows shell, "cmd" must be loaded. The name of the command shell varies by operating system.
