You also need to be away that referring to positional parameter $25 will usually end up being interpreted as ${2}5, i.e. the value of parameter two, followed by the literal value 5.

Someone in their wisdom here managed to code scripts that look like this:-
Code:
date_req=$22013

The idea being that the month is passed in as positional parameter 2 and the year is appended. Apart from looking awful, of course we then ended up editing the script each year - oh, and the year was not necessarily the calender year that the process was running in either.

It works for us (very badly and will be replaced soon) but you might get very confused by the use of:-
Code:
title=$25
echo $title

.... giving you the output gM5

cal

CAL(1)							    BSD General Commands Manual 						    CAL(1)

NAME

     cal -- displays a calendar

SYNOPSIS

     cal [-smjy13] [[month] year]

DESCRIPTION

     Cal displays a simple calendar.  If arguments are not specified, the current month is displayed.  The options are as follows:

     -1      Display single month output.  (This is the default.)

     -3      Display prev/current/next month output.

     -s      Display Sunday as the first day of the week.  (This is the default.)

     -m      Display Monday as the first day of the week.

     -j      Display Julian dates (days one-based, numbered from January 1).

     -y      Display a calendar for the current year.

     A single parameter specifies the year (1 - 9999) to be displayed; note the year must be fully specified: ``cal 89'' will not display a calen-
     dar for 1989.  Two parameters denote the month (1 - 12) and year.	If no parameters are specified, the current month's calendar is displayed.

     A year starts on Jan 1.

     The Gregorian Reformation is assumed to have occurred in 1752 on the 3rd of September.  By this time, most countries had recognized the ref-
     ormation (although a few did not recognize it until the early 1900's.)  Ten days following that date were eliminated by the reformation, so
     the calendar for that month is a bit unusual.

HISTORY

     A cal command appeared in Version 6 AT&T UNIX.

OTHER VERSIONS

     Several much more elaborate versions of this program exist, with support for colors, holidays, birthdays, reminders and appointments, etc.
     For example, try the cal from http://home.sprynet.com/~cbagwell/projects.html or GNU gcal.
