• file number
• string_variable_1
• string_variable_2

Description

Reads a line from an open text file (opened for Input through a bound file number) and stores it in a string variable.

A line of text ends at, but does not include the end of line characters. An end of line character may be the LF character (Chr(10)) or the CRLF character pair (Chr(13,10)).

Two syntaxes are available:

Note:

- Using Line Input # is naturally dedicated to Input Access file mode. - It is also allowed in Binary/Random Access file mode, but this was never well tested and results may vary.
