+-(-+------+-+--------+-)-+
+-line-+ +-,count-+
Returns the next
[count]
lines. The
count must be 0 or
1 . The stream advances the read
pointer. If you omit
[count]
, it defaults to
1 . A
[line]
number may be given to set the read position to the start of a specified
line. This line number must be positive and within the bounds of the stream,
and must not be specified for a transient stream. A value of 1 for
[line]
refers to the first line in the stream.
If the stream is not already
open, then the interpreter tries to open the stream for reading and writing. If
that fails, the stream is opened for input only.
