Tip of the Day: Enhanced ECHO to Optionally Suppress Feedback
Product.......: R:BASE X and R:BASE X Enterprise (Version 10)
Build.........: 10.0.2.20731 or higher
Section.......: Commands
Keywords......: ECHO, Settings, FEEDBACK
Did you know the ECHO operating condition can optionally suppress
commands during processing,
to improve the readability of an echoed output stream?
The ECHO settings displays or suppresses commands as they are
processed. Specify ON to display
commands; specify OFF to turn off the command display.
Use SET ECHO as a debugging technique as you develop a command file.
With ECHO set on, you can
see the commands as they are processed when you run a command file.
SET ECHO works only when
the command file is a non-binary procedure file.
Enter SET ECHO ON at the beginning of the program. Then, when the
program runs, R:BASE displays
each command as it is interpreted and, if needed, runs it. Set ECHO
off to suppress command
display. You can also direct the output to a printer or a file before
you set ECHO to on. Then,
when the command file runs, the commands and any errors are saved
either in printed form or in
a file you can look at.
Echoing output can optionally be suppressed if a command starts with
the "@" character, to
improve the readability of an echoed output stream, for example, the
echoing of the SET ECHO OFF
command. Do not put any spaces in front of this character to make the
output appear correctly.
When R:BASE runs the commands below in a file, you see the WRITE
command display along with the
message.
CLS
SET ECHO ON
WRITE 'This is a message'
SET ECHO OFF
To display the WRITE command along with the message, and without the
SET ECHO OFF echo output,
use the following:
CLS
SET ECHO ON
WRITE 'This is a message'
@SET ECHO OFF
One of the most important aspects in business growth is your
company's data, and no one else
has more invested in your success than R:BASE Technologies. Invest
forward with R:BASE!
