IBM 5150 User Manual

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. ~
