Re: How to get a character?

[Jeff Carter <spam.carter.not@spam.innocon.com>]

Again, I see people recommending Ada.Text_Io.Get_Line as the way to
perform the "Press Enter [or Return] to continue:" function. This is
incorrect. When, in response to this message, the user types enough
characters to fill the Item parameter to Get_Line, the program will
continue before the user presses Enter [or Return]. If the user
mistakenly types ahead, this can be a significant problem.

In Ada terms, the desired behavior is for the program to wait until the
user inputs a line terminator on standard input, and consume that line
terminator. The Enter [or Return] key is how the user inputs a line
terminator. The correct way to wait for and consume a line terminator on
standard input is

Ada.Text_Io.Skip_Line;
