how to edit the Truclient script

I am new to this tool.

I have recorded a script throgh truclient in Loadrunner.

i am not able to edit it, so can't we edit the truclient script once recorded?

i want to comment some line of code in that script so that if i run that it will skip it and move further.

is there any settings i have to make to edit the truclient script.

Thanks in advance
