Text_io, beginer's question

Text_io, beginer's question

[Xuren Huang]

Wrote a loop to read in strings along with other types of variable from
keyboard.  Except the first time it was encounted in the loop, the line
" Text_IO.Get_Line(String, StringLength)" would not be executed.  Any
idea how to fix that?  BTW, I am using win95 GNAT v.304a.  Thanks in
advance.

Please show us the loop and perhaps some of the code before the loop, and
we'll try to help you.

Stick a Text_IO.Skip_Line in the code right before the loop. This might work.
I have had similar problems using Get_Line and sometimes a Skip_Line will help.
I don't know why, but if it works it works.

Hope this helps.

Try this:

fname        : fname_type := (others=>' ');
fname_ndx : natural        := natural'first;

text_io.get_line(fname,fname_ndx);
if fname_ndx = fname'last then
   text_io.skip_line;
end if;

Indiscriminant use of text_io.skip_lines commonly cause more problems than
they solve.  If you want to know why, send me some email and I'll send you
a personal reply.
