Uddhavesh -
Also not a problem, out to the limits of 4 byte integer arithmetic, or 2,147,483,647. I wouldn't try more than that ;-). I know the print format overflow is annoying. I will bump up the fields in pmemd 3.1.

Hello Sir,
The NSTEP Format is also overflowing (See attached o/p). Will it affect analysis part. Kindly, let me just know what are the consequences of this thing.
NSTEP =995000 TIME(PS) = 2530.000 TEMP(K) = 300.66 PRESS = 25.35
Etot = -109448.4709 EKtot = 25518.1918 EPtot = -134966.6627
