Copying from GrADS

[Hyacinth Cyprain Nnamchi]

Dear users,
I am using GrADS 2.0.a7.oga.2 on windows. 
Please what is the command to copy from the screen to another document.

This is what I mean:
I have a .nc file which I have re-written to .dat for use. However, the x,y,z levels for the original data (.nc) are listed when I issue the "q ctlinfo" command. So I need to copy them (I mean the x,y, z levels) to the ctl file of the new dataset (.dat) which I have just written.This is the problem.

Any suggestions, please.

Hyacinth
