integer input from text file

integer input from text file

[dumur]

My problem is that I got to read a time string from a text file. It is
in the form 12:34:45 Hour:Minute:Second. I want to get each part one
by one with

Ada.Integer_Text_IO.Get(File=>input_file, Item=> Hour);
Skip; -- skips the ":" character 
Ada.Integer_Text_IO.Get(File=>input_file, Item=> Minute);
Skip;
Ada.Integer_Text_IO.Get(File=>input_file, Item=> Second);

But the colons(:) troubles me here. If I use "," or "." instead of
colons it works but there will be colons in the input. What is the
problem? Is there any special meaning of colons(:) in Ada? Thanks.

Yes. See J.2(3) in the RM.

12:34:45 is equivalent to 12#34#45, that is, the base-12 number 34 (40 
decimal) followed immediately by the base-10 number 45. If you have a 
24-hour clock, hours of 00-01 and 17-23 will cause errors because Ada 
only does bases of 2-16 automatically.

You probably ought to read the whole string and parse it yourself.
