lines

What does "lines" mean here?
Context:
Though they seldom had any lines, Fred and Adele danced their way through a number of musical revues until in 1922 they were cast in "For Goodness' Sake" with songs by George and Ira Gershwin. Although they had sixth billing, they stole the show.

They didn't have to talk much, I believe; they had not much text.

Thanks for replying.

Text = topic?

they seldom had any lines = they were taciturn?

No, the text is what actors must learn to play in dramas, movies etc. so that they know what to say and when to say it.

I agree with FRC.

lines refers to dialogue (i.e., the lines/sentences of dialogue in the script).

All the best, :D
