[petsc-users] How to load IS from file

[Saurabh Chawdhary]

Hi guys,
With ISView we can dump the IS into a viewer and file and save it. But 
how can we load the IS back from file into the code.
ISLoad is a function in current petsc version 3.5 but it doesn't exist 
in version 3.4.5. Is there an alternate way to di the job?
All we want is the ability to save an IS in current program and read it 
back later. How can this be done in Petsc 3.4.5?
Help! Help!

Thanks,
Saurabh
