Information

Syntax

(string, endOfFile) = Streams.readLine(fileName, lineNumber)

Description

Function readLine(..) opens the given file, reads enough of the content to get the requested line, and returns the line as a string. Lines are separated by LF or CR-LF; the returned string does not contain the line separator. The file might remain open after the call.

If lineNumber > countLines(fileName), an empty string is returned and endOfFile=true. Otherwise endOfFile=false.
