With the arrival of typecasting a generic approach became possible, making ord mostly obsolete. Historical note: Originally, Pascal did not have typecasts and ord was a necessary function in order to do certain operations on non-integer ordinal types.

Uses Classes, SysUtils, LResources, Forms, Controls, Graphics, Dialogs, ExtCtrls, var l : boolean function check_affirmation () : boolean var k : string begin Writeln ( 'To quit the application do NOT use CTRL-C!

The computer programming languages C and Pascal have similar times of origin, influences. #Free pascal ord codeThe code can be compiled on different environments using conditional compiles, like this: The language construct ord(someVariable) evaluates to the index of any ordinal type, including, but not limited to any integer type and sub-ranges thereof, char, boolean, or any enumerative type. So you are using arbitrary starting value (here perhaps zero because l is. But I see a single place where you do changing (increment) this variable and don't see any l initialization. The only array s in indexed by variables that depend on l value (weird name, BTW). Therefore, this article will basically cover hardware access methods on different platforms. I googled this: 201 : range error, so you probably go out of array bounds. Uniform multi-platform access to hardware devices is not implemented by the Free Pascal Runtime Library (RTL) or by the LCL - the underlying operating systems are often different enough to make that very difficult. #Free pascal ord serialThese devices include, but are not limited to: ISA, PCI, USB, parallel port, serial port.
