Display procedures and IDEs

Display procedures and IDEs

[Jamie]

Hi,

I use the GNAT compiler under a Win95 IDE, and have 
experienced some strange problems when attempting
to use display procedures such as 'Set_Col' and 
'New_Page' etc. 

Instead of the relevant function being executed all
I get at the DOS prompt is a strange message such as
'Got XX' where XX is a number ranging from 4 to around
14.

What's happening here then? 

I am quite literally tearing my hair out, as I'm 
attempting to teach myself the language in preparation for a university
course I'm shortly to be taking.

As an aside, are there any IDE's available that run under DOS or Windows
which allow single stepping and tracing, watches etc. ??

An IDE such as this would be a great help to me as I'm from the C/C++
stable where I have taken features like this for granted.

Thanks for any help in advance,

Jamie.

Well, actually, Ada does not have 'display procedures'.
What you are probably trying to use are Text_IO procedures,
which address structured text files.

As you are on windows, get the nt_console package from my
homepage at http://stad.dsl.nl/~jvandyk, this should do
what you want.

As you will find out, debugging tools are much less needed with Ada than
with languages like C and C++. Nevertheless, if you are using the ObjectAda
compiler, it does include such a debugger. If you are using the GNAT/AdaGIDE
combination, download the debugger from the same site you got GNAT.

Success,
Jerry.
