Commands: ENTER to advance, numeric value to convert, Y/N to continue, RESET to restart.
P1CBF.EXE - CelsiusConversion (1995)
DOS Roots Lab
Celsius Conversion, Rebuilt from 1995
One of my earliest Pascal programs: prompt for a Celsius value, run the conversion formula, and display the Fahrenheit result.
Original Program Intent
P1CBF.PAS is a focused beginner utility. It introduces typed numeric input,
arithmetic, and formatted output in a DOS console flow.
The core behavior is simple but foundational: read a number, apply a formula, and print a clear human-readable result.
Original Pascal Logic
1) Input Prompt
write ('Please enter a Celcius temperature --> ');
readln (Celcius);2) Conversion Formula
Faren := (Celcius * (9/5)) + 32;3) Result Output
writeln (Celcius:1:1,' Celcius equals ',Faren:1:1,' Farenheight.');View longer 1995 source excerpt
program CelciusConversion(input,output);
var
Celcius:real;
Faren:real;
begin
writeln;
writeln ('This program Converts Celcius temperatures');
writeln ('to Farenheight temperatures & will then');
writeln ('display both on the screen.');
write ('Please enter a Celcius temperature --> ');
readln (Celcius);
Faren := (Celcius * (9/5)) + 32;
writeln (Celcius:1:1,' Celcius equals ',Faren:1:1,' Farenheight.');
end.Developer Notes
What Stayed True
- Single-purpose formula workflow from typed input.
- Immediate output after one conversion step.
- Simple prompt-response console tone.
What Changed for Web
- Session runs in a browser-based DOS terminal shell.
- Invalid numeric input is handled with inline DOS-style errors.
- RESET replays the startup flow without reloading the page.
