Y - Why?

Syntax:

Description:

Y repeats or expands on the most recent error message issued by FRED. For example, FRED's normal error messages tell you what the error was but not where it was; Y tells both what and where. If the error occurs during an I/O access attempt, Y explains why the access failed. "." is not changed by the Y command.

Y also tells you the context of an error: the line that was executing at the time the error occurred. This is particularly helpful if you are running a buffer program.
