[Tugindia] Custom page format

[Nilay Bhatt]

hello everybody,
 i want to write some memo/description in a customized page format,
i.e. diff. margin settings for diff pages. 
For example,
page -1
+ -------------------+
 | |
 | |
 | -------------- |
 | | | |
 | | | |
 | -------------- |
+--------------------+
 page-2
+--------------------+
 | -------------- | 
 | | | |
 | | | |
 | -------------- |
 | |
 | |
 | |
+-------------------+
and so on...........
  i tried to write a class file like the following one........
==============================
\LoadClass[11pt,legalpaper]{article} 
\ProvidesClass{crtemp} 
\usepackage{ifthen} 
\setlength{\oddsidemargin}{-0.25in} 
\setlength{\textwidth}{7.0in} 
\pagestyle{empty} 
\setcounter{page}{1} 
\ifthenelse{\value{page} = 1}% 
{\setlength{\topmargin}{7.5in} \setlength{\textheight}{1.5in}}{} 
\ifthenelse{\value{page} = 2}% 
{\addtolength{\topmargin}{-7.5 \topmargin} 
\setlength{\textheight}{7.5in}}{} 
=========================================
 but it does the job for the 1st page only and maintains the 
format for all other pages.
 can anybody help me out on this issue??????
hoping to get a +ve reply
