## Description

SeekEoln returns True is the file-pointer is at the end of the current line. It ignores all whitespace. Calling this function has the effect that the file-position is advanced until the first non-whitespace character or the end-of-line marker is reached. If the end-of-line marker is reached, True is returned. Otherwise, False is returned. The end-of-line marker is defined as #10, the LineFeed character. If the parameter F is omitted, standard Input is assumed.

## Errors

A run-time error is generated if the file F isn't opened.
