IBM 5150 User Manual

For another example, perhaps we tried this:
dir 8*.*
These files would be listed:
80PRICES.AVG
81PRICES.JAN
81 PRICES.JU L
81PRICES.AUG
And if you type:
dir *.*
all the files would be listed.
You can use
both global filename characters together.
For example, if you type:
dir ??p*.a*
you would see these files listed:
79PRICES.AVG
80PRICES.AVG
81PRICES.AUG
Global characters are fun, but you need to be careful
both in naming your files and in using them-you may
get results
you didn't expect!
