Thankx again. Actually combining the two was what i attempted first, but
then latex requires further preprocessing, but pdftex doesnt. Moreover i
want to remove some of the latex tags that i insert into a draft paper
(version info etc), for which it is essential to determine whether it is
slides or paper i am dealing with once and use it again later (Is
repeting that piece of code the only option). 

Is there any way i can test this once and set a variable and then use the
corresponding processor for the file. (i guess this is dumb on my part,
there must be a way!)

Thankx in advance,

Best wishes
