Similarly, the output will be even more pleasant at 64 columns:

Fig. 20 – CAT EXP output in 64 columns

It's evident that the columns are really 4 and they only get broken down in two lines in order to fit. Let's now examine the use of the – switch. If you type:

CAT -

Your display now will look similar to this:

As you can see, filenames are now clearly separated at the 9th character by a dot followed by a 3 letter type. In order to demonstrate what happens with a larger filename we could write a simple program and save it as follows:

10 PRINT "Hello World"

SAVE "This Is A Hello World Program.bas"

Then try both CAT and CAT - as follows:

CAT - "th*.bas": CAT "th*.bas"

(Here we're also demonstrating the use of wildcards for the first time). Your display will then be:
