|command: ECHO |
|use: The batch command ECHO lets you choose whether or not to have |
| the commands in your batch file displayed on the CRT screen as they |
| are performed. ECHO is also used for message display (no commands |
| are shown). SEE NOTES SECTION BELOW. |
| |
|how: Type: ECHO ON O-R ECHO OFF [for message sequencing] |
| |
|examples: REFER TO ANY TIMEMASTER .BAT FILES ON THIS DISK |
| |
|notes: Commands in a batch file are normally displayed as they are |
| performed by your computer. If you enter ECHO OFF into a batch file |
| the commands are not displayed when they are performed. Command dis-|
| play while a batch processing file is operating can be distracting. |
| If you display the commands have a good reason for it! |
| A little known (useless?) feature is to type: ECHO <ret> at the |
| prompt, which displays current status of ECHO. If you type ECHO OFF |
| <ret> the prompt will disappear. Type:ECHO ON to restore! |
| If ECHO is set to OFF,you can use ECHO <your message>to display |
| text on screen. You can use this ONLY in a batch processing file. |
| ECHO sends a message to the CRT screen. It helps organize and ex- |
| plain on the screen when a batch file executes. Normally, all batch |
| file commands would show on the screen as the file performs. To pre-|
| vent this echoing type: ECHO OFF at the beginning. In particularly |
| long batch files you may have to do this after several or all of the|
| message echoeing sequences. This becomes especially true when you |
| are commanding the display of multiple page ascii text files or |
| when showing long files a page at a time with the DOS MORE command. |
| Your test run of the batch file you create will show you whether or |
| not additional ECHO OFF cmds are necessary. We always"follow-on"the |
| ECHO OFF with a CLS on the next line. This keeps the on-screen co- |
| mmand distraction to a minimum. If you examine the .BAT & .EX files |
| on this disk you will see the use of ECHO in TIMEMASTER'S efforts. |
| When ECHO is OFF none of the actual DOS commands in the batch |
| file will show on the screen. To display a message put it after tbe |
| command: ECHO . . .MY DOG HAS FLEAS!. . . |
| (Watch the placement, trying for message centering on the screen). |
| As you will see in REM.HLP,that command also displays messages. |
| You will learn,however, that is not the case if ECHO is OFF. |
