.II "letters, print"
The command
.B letter
prints form letters from a standard letter and a mailing list.
It is obsolete, because the command
.B report
is so much more powerful and easier to use; but it is retained for
compatibility and as an example of shell programming.
.PP
.B letter
is a shell script, so you can be easily changed it
to handle different lists and letters.
To modify it, copy
.B letter
from
.B $RDB/bin/letter
to your local directory, then use your text editor to edit it.
Then you can modify it with a text editor
to handle any special features of your mailing list and letters.
.SH Example
If you have a file called
.B maillist
that looks like this:
.DM
Name Ronald McDonald
Company McDonald's
Street 123 Mac Attack
City Memphis
State TENN
ZIP 30000
Phone (111) 222-3333
.sp \n(pDu
Name Chiquita Banana
Company United Brands
Street Uno Avenido de la Reforma
City San Jose
State Costa Rica
ZIP 123456789
Phone 1234

.DM

.DE
.PP
And
.B letter.2

The following sample letter program prints out the mailing name
and address, and the salutation \fBDear \fIName\fR.
It then \fBcat\fRs
.BR letter.1 ,
echos the company name, and finally cats
.BR letter.2 .
.B letter
writes its output to temporary file
.BR TMP ,
then
.BR nroff 's
the

file to the standard output.
