LINES
(int)Character height of terminal
LINES
returns the cell height of the terminal.
This is a reserved variable so it cannot be changed.
The Murex controlling terminal is assumed to be the terminal. If
Stdout cannot be successfully queried for its dimensions, for example
Murex is a piped rather than controlling a TTY, then $LINES
will generate an error:
