.SH Example
Here we convert a string to upper case:
.DM
	uppercase little words
.DE
.PP
This displays
.DM
	LITTLE WORDS
.DE
.PP
on the standard output.
.PP
If the file
.B lowers
contains the text
.DM
	these are all lowercase.
.DE
.PP
then the command
.DM
	uppercase < lowers
.DE
.PP
prints the following on the standard output:
.DM
	THESE ARE ALL LOWERCASE.
.DE
.SH "See Also"
.B
