Integer to String Conversion?

Integer to String Conversion?

[bwefler]

Does anyone know an Ada-83 compatible method to convert an integer to a
string, so that the string may be concatenated with another string, and the
resulting string passed as a parameter to a function call?  (Note: I am not
talking about using Text_IO or Integer_IO in this case;  I simply want the
result to be a string.	Another function will take care of the string.)

Thanks.

The usual way is with the 'Image attribute, but you may need to exercise
a little caution, given that it is defined to return either a leading
minus sign or a leading space and in either case, whatever you pass it
to has to deal with that appropriately.

See the Ada83 LRM, 3.5.5(10)

For the type "Integer" and an object "X" of type "Integer" you would
have a function like this:

Integer'Image (X)

This will return the character string.

There is also, within Text_IO.Integer_IO a procedure "Put" which can put
an integer into a string, rather than to a file. This is typically more
work than the 'Image solution.

Send_Message("Count has reached" & Integer'Image(Count));
for example?

It sounds like you want the "'image" attribute.

I highly suggest you go through Annex A of your Ada 83 LRM (available online
at http://www.adahome.com/LRM/83/RM/rm83html/ ) and read about *all* the
attributes. There are all sorts of goodies in there to make your life easier.

This has to be the number one FAQ these days:

  X : Integer;
...
  Put ("this is a string" & Integer'Image (X));

Integer'Value goes the other way, and converts a string into an
integer.  It'll even convert alternate bases, ie

  Integer'Value ("16#A#")  returns the value 10 (decimal)

Not only is this question frequently asked, but every time
it is asked, we get dozens of replies (often from people
who are obviously NOT following threads before answering).
Perhaps we should take it in turns to be the official
'Image answerer for the month.

Seriously, it would really help if people would thread
follow before posting answers to questions like this
