Helps And Hints - IBM 5150 Manual To Operations

Helps and Hints
We are ending this chapter with a few hints-maybe
they will save you some trouble or help you as you use
your IBM Personal Computer.
•
Make backups regularly.
(We have repeated this already, but since this is our
last chance, we are saying it one more time.)
• Sometimes, commands do not work as you expected
because a file specification was typed incorrectly.
- Check your typing.
- Do you have the correct diskette in the drive?
- Check the directory of the diskette.
- Has the correct diskette drive been specified or is
it being assumed? Has the colon been included?
- Has the filename been spelled correctly?
- Have you forgotten to use the extension?
(In the case of BASIC program files, for example,
it is easy to forget the .BAS that BASIC uses for
an extension.)

• If a command still doesn't work, read the book
again.
• Be careful with global filename characters, especially
in the ERASE command. If you insist on using them:
- Use the DIR command first with the global
filename specification, to test the results.
- Check to see that these are really the files you
want to delete.
- Then, go ahead.
• Print a directory frequently (if you have a printer)
and store the listing with the diskette. The labels
are usually too small to hold everything you want
to write on them.
