Using Turbo Pascal

Hello,
>I am new to Pascal programming and the Turbo Pascal compiler ver. 7.0. For
>a program I've compiled, an outline of the source code I'm using goes like this:-
>....
>BEGIN
>
>  Readln (some input);
>  some processing work...
>  Writeln:(some output);
>END;
>
>There's no problem with my source code, just that while running the
>program, after entering the input data, pressing carriage return wouldn't
>bring about the output supposed to be displayed on screen. Instead the
>program automatically terminates and I'll have to rerun the program again
>in order to view the output produced from my previous input. What should I need to do to remedy this problem? Thanks.

You are running inside the Turbo Pascal development environment? This has been a long time but there is a Windows menu and if you select the output window you should be able to look at it without rerunning the program. Try F5 (or was it Alt-F5...think that was launch shell commmand).

Alternative is to put a getch() command at the end of the program so the program doesn't terminate until you press another key. That way the output window retains the focus.

getch()  mmmm that sounds like C language.

Before the last "end" put:

write('Any key to finish');
readkey; { You're going to look this one up in the help 'cause I can't remember in which unit it is, and I don't have TP here. }

Hope it helps.

ReadKey! That is it. Too long away from Pascal. It is in CRT in 5.5 (can't say for 7.0) and Alt-F5 is the output window toggle (had to fire up TP to see).

Brings back memories. Obviously _fuzzy_ memories but memories all the same.

Good catch, Jack.

Oh yes! That old and beloved blue screen with yellow chars!

So different from those other blue screens W95 got us used to! =)

To bcl,
It didn't work with getch()command though I didn't get any compiler's error messages. I have also tried Alt+F5 before but it just didn't work out the way I wanted.The idea with using Readkey was good as I just don't expect the window to disappear right away after typing in the input, before the output can be seen displayed.

Thanks alot...
