(Shahab Raza Khan) asks for ways generate and/or modify batch files.
Some useful techniques are:

Technique #1:
------------
Use batch file parameters.  E.g.,

prompt> call batch %ENV-VAR%

This call necessarily occurs within another batch file; otherwise,
ENV-VAR won't be replaced by its value


Technique #2:
------------
prompt> echo stuff1 %ENV-VAR% stuff2 >>temp
prompt> copy prefix+temp+suffix target.bat
prompt> call target
prompt> del temp
prompt> del target.bat


Technique #3:
------------
prompt> edlin batchfil.bat <commands.ed >NUL

where commands.ed contains 
	
		1,#roldstuff1^Znewstuff1
		1,#roldstuff2^Znewstuff2
       		...
		e

Since commands.ed contains control characters, you have to use the /B
switch when you edit it.  That is,

		edlin /B commands.ed

If you're still using MSDOS 3.3 (as I am), the B in /B must be in the
upper case.  Also, the simplest way I know to print commands.ed is:

		edlin /B commands.ed >print.fil
		l
		q
		y

Another caution:  edlin won't operate on a read-only file,
so if you set the read-only attribute, you won't be able to
inspect commands.ed directly.

Hope this helps,
