Overview
This readline(f) function will read a line (delimited by the new line character) from a file with handle f. The file handle maintains its position in the file, so after a call to readline the position pointer will be incremented.
Example
#include <io> var f:=open("hello.txt","r"); var u:=readline(f); close(f);
