- Scan is not warranted in any way although it seems safe enough to me.
- Scan displays the ASCII portions of any file. It ignores leading spaces,
- isolated punctuation, leading digits, and any ascii string less than 4
- characters long. The idea is to give you a quick look at the ASCII
- messages in a file without showing you a lot of garbage. Ignoring
- strings less than 4 characters long still gives you some garbage and
- occasionally skips things you might like to see but it seems to be
- a fair compromise.
-
- Scan may be useful in guessing at undocumented features of .com
- and .exe programs (like printing 'ARF ARF -- GOT YOU' after formatting
- your hard drive).
-
- It's also fun to scan commercial programs (especially Microsoft's)
- looking for unusual messages. WordPerfect4.1 is a trip -- it includes
- things like "There are no phonetic rules for this language." (in case
- aliens from outer space try to run the spelling checker),
- and one lengthy message about how you've probably lost all your work
- and may have to reboot.
-
- Command.com is also interesting:
-
- "Intermediate file error during pipe"
- "Cannot do binary reads from device"
-
- although some of the messages are truncated because the high bit is set
- on some characters a la WordStar. This has been fixed in DOS 3.x
-
- Of course scan can also be used to read a text file although LIST is
- probably a better choice since it is faster and allows paging backwards.
-
-
- Scan shows the data continuously.
-
- Use CTRL S to pause
- CTRL C to abort
