gettxtmsgfile:msgnum[default_message]
Obtain the message that resides in file msgfile and whose
message ID is msgnum. msgnum is a number from 1 to n,
where n is the number of messages in msgfile.
gettxt searches for msgfile in directory
/usr/lib/locale/locale/LC_MESSAGES, where locale
is the language in which the message strings have been written.
The value of locale is set by environment variable LC_MESSAGES,
or failing that, the LANG environment variable. If neither is set,
locale defaults to a directory named C. If gettxt fails,
it displays default_message or (if none is specified) the string,
"Message not found!!"
