"Sub" is short for...?
-
Hi all. This may be a silly question, but does anyone know definitively what the keyword "Sub" in Visual Basic is short for (or, perhaps "derived from" is a better expression)? Does it come from "subroutine", "subprogram", something else? Or did the VB creators just call it "Sub" with no intent to reference earlier forms of BASIC? Or is "Sub" a bonafide keyword for BASIC (and not just Visual Basic)? I'm not sure why I want to know... just curious, I guess.

I'm guessing it means subrouting. From earlier forms of basic "GO SUB"

Hi Colin. That was always my guess too - but I wondered (call it a geek obsession) if there were a definitive history to it.

I've always though it was 'subroutine', and took it for granted...now I wonder... hey...slang is the vernacular for the vernacular...wow

It is short for "subroutine" - has been as long as I've been involved with computers.

Page 422, chapter 9, of "Visual Basic 6 Complete", Table 9.5: Statements Supported in VBScript. Sub - Declares a Subroutine Looking at the example provided, a subroutine is a division or seperate event happening inside of an "event procedure" as described below. Page 42, chapter 4, "Visual Basic 6 For Dummies" In Visual Basic lingo, subprograms are event procedures (although some programmers may call them subroutines). So my understanding would be that a "Sub" is actually an "Event Procedure" and a "Subroutine" is inside of an event procedure and seperated by a marker consisting of an apostrophe followed by a tilde ('~). The example is provided on page 441, chapter 9, of "Visual Basic 6 Complete". Hope this helps, Garner

It's short for Subroutine. It's an extension to the original BASIC language. In BASIC there are no subroutine structures, only the GOSUB command that jumps to a line number and returns using the RETURN command:
10 GOSUB 40 20 END 30 REM Here follows the subroutine: 40 PRINT "Hello world!" 50 RETURN--- b { font-weight: normal; }
