///1GET
|
||
|
|
|
||
|
|
Syntax:
|
||
|
|
|
||
|
|
GET {CONSOLE INPUT FROM} FILE filespec{[{ECHO|NO ECHO} | SYSTEM]}
|
||
|
|
GET {CONSOLE INPUT FROM} CONSOLE
|
||
|
|
|
||
|
|
Explanation:
|
||
|
|
|
||
|
|
GET directs the system to take console input from a file for the
|
||
|
|
next system command or user program entered at the console.
|
||
|
|
|
||
|
|
Console input is taken from a file until the program
|
||
|
|
terminates. If the file is exhausted before program input is
|
||
|
|
terminated, the program looks for subsequent input from the
|
||
|
|
console. If the program terminates before exhausting all its
|
||
|
|
input, the system reverts back to the console for console input.
|
||
|
|
|
||
|
|
With the SYSTEM option, the system immediately goes to the
|
||
|
|
specified file for console input. The system reverts to the
|
||
|
|
console for input when it reaches the end of file. Re-direct
|
||
|
|
the system to the console for console input with the GET
|
||
|
|
CONSOLE INPUT FROM CONSOLE command as a command line in the input
|
||
|
|
file.
|
||
|
|
|
||
|
|
///2Options
|
||
|
|
|
||
|
|
ECHO specifies that input is echoed to the console. This
|
||
|
|
is the default option.
|
||
|
|
|
||
|
|
NO ECHO specifies that file input is not echoed to the
|
||
|
|
console. The program output and the system prompts are
|
||
|
|
not affected by this option and are still echoed to
|
||
|
|
the console.
|
||
|
|
|
||
|
|
SYSTEM specifies that all system input is immediately taken
|
||
|
|
from the disk file specified in the command line. GET
|
||
|
|
takes system and program input from the file until the
|
||
|
|
file is exhausted or until GET reads a GET console
|
||
|
|
command from the file.
|
||
|
|
|
||
|
|
///2Examples
|
||
|
|
|
||
|
|
A>GET FILE XINPUT
|
||
|
|
A>MYPROG
|
||
|
|
|
||
|
|
Tells the system to activate the GET utility. Since SYSTEM
|
||
|
|
is not specified, the system reads the next input line from
|
||
|
|
the console and executes MYPROG. If MYPROG program
|
||
|
|
requires console input, it is taken from the file XINPUT.
|
||
|
|
When MYPROG terminates, the system reverts back to the
|
||
|
|
console for console input.
|
||
|
|
|
||
|
|
A>GET FILE XIN2 [SYSTEM]
|
||
|
|
|
||
|
|
Immediately directs the system to get subsequent
|
||
|
|
console input from file XIN2 because it includes the SYSTEM
|
||
|
|
option. The system reverts back to the console for
|
||
|
|
console input when it reaches the end of file in XIN2. Or
|
||
|
|
XIN2 may redirect the system back to the console if it
|
||
|
|
contains a GET CONSOLE command.
|
||
|
|
|
||
|
|
A>GET CONSOLE
|
||
|
|
|
||
|
|
Tells the system to get console input from the console.
|
||
|
|
This command may be used in a file (previously specified in
|
||
|
|
a GET FILE command), which is already being read by the
|
||
|
|
system for console input. It is used to re-direct the
|
||
|
|
console input back to the console before the end-of-file
|
||
|
|
is reached.
