Hi Bala,
There's no specific command for it, but you can use the generic "setattr" command to do it.  Say you want to label residue 3 in chain A with "my text":

setattr r label "my text" :3.a

Friends,

I would like to know how to use our own strings with 3D label. suppose if i give 'rlabel :3', residue 3 is labelled as LEU 3. But i want to pass a string that should replace LEU 3. Hope i am clear. I know 2D label can use a string but i wish to use string especially with 3D label.
