Paradox

Paradox is a language concept by User:Maxsteele2 which is like a cross between BASIC and TwoDucks.

Description
Paradox is different to the (possibly) average programming language by requiring some lines not to function.

Hello, World!
10 set20:"Hello World" 20 This line is skipped 30 print20 40 terminate This program results in; Hello World Line 20 is skipped, because the number 20 was given the value of "Hello World". If the line was written as such; Hello World This line is not skipped. ...then the ine would not be skipped, and as a result, this; Error: "This" is not a command Error: "line is not a command" is not an object. Hello World

Quine
Quines are easier to do in Paradox than other languages. 10 set30:10thru40 20 print30 30 This line will not run FIRE MAH LAZER BLAAA 40 terminate Notice that in line 10, there were no quotation marks. This is important, as if there were quotation marks, the result would have been much less impressive.

Why?
This feature is useful for getting information from databases. For instance: 10 goto 60 20 Space is pressed. 30 terminate 40 Space is not pressed. 50 terminate 60 if input="space" 70 goto 20 80 goto 40

Input Terminator
This line will terminate if input is detected from the spacebar. 10 if input="space" goto 30 20 goto 10 30 terminate

I forgot what this one was for...
