Delphi ^A syntax: Documented, implied, or undocumented? – Stack Overflow

Posted by jpluimers on 2019/12/12

The syntax is documented. In the Turbo Pasal 3 documentation, i.e. the Z80 era.

Source my answer to [WayBackDelphi ^A syntax: Documented, implied, or undocumented? – Stack Overflow (I have added some WayBack Internet Archive links below) as it is from the Turbo Pascal era where the caret was introduced to support control characters:

This is from long ago as an escape character to enable you to have consts for control characters in a more readable way.
const
  CtrlC = ^C;
begin
  Write(Ord(CtrlC));
end.

This defines a Char constant with value #3, then writes 3 in Borland Pascal 7, and I remember seeing it years before that too.

I just checked the Turbo Pascal 5.0 and Borland Pascal 7.0 languages guides, but could not find it, so it seems undocumented.

Edit: I do remember this was a Borland thing, and just [WayBack] checked: it is not part of the ISO Pascal standard (formerly this was ANSI Pascal Standard, thanks Sertac for noticing this).

It [WayBack] is documented in the Free Pascal documentation [WayBack].

SGI uses the backslash as escape character, as per their docs [WayBack].

More Edit: I found it [WayBackdocumented in Delphi in a Nutshell and the [WayBackDelphi Basics site.

Found it: Just found it on page 37 of the Turbo Pascal 3 Reference Manual [WayBack].

(Marco van de Voort found the Free Pascal documentation)

It in fact originates in the 1984 Turbo Pascal 1 edition, as per the [WayBack] Turbo_Pascal_Reference_Manual_Feb84.pdf:

6502 emulation: the ICE, or in-circuit-emulator…

Posted by jpluimers on 2019/02/05

On my list of hardware things to try:

[WayBack] a different take on 6502 emulation: the ICE, or in-circuit-emulator… – mos6502 – Google+

Basically it consists of three parts:

A (hardly) limited Turbo Pascal Compiler (and large parts of the IDE!) in JavaScript.

Memories from the CP/M era (:

Code is on GitHub.
