Re: Re: Is it me?

Hi,

Sorry, its a mistake...
(I should have tested it first...)

> onetwo = "$one\$two"
> say "onetwo: $onetwo"

The above does correctly result in 12.

In the first line, g4c will stop reading the variable name at "\", so
will evaluate it as "$one", ie "1".

Assignments work the same whether its Say or =

Also, the debug output are the raw variable contents (AFAIR)

Best regards
Dimitris

If what you say below is true, I don't understand why the first output would be "12" unless variable assignment works completely differently from "say". Looking at the debug output, it says SETVAR ONETWO 1$two. Is that the debug output from my assignment onetwo = "$one\$two"?

If a variable contains "one$two" I expected say to tell me that, not look for a variable one$two. But I don't usually expect that in day-to-day programming - it was just because I wanted to inspect the direct contents of these variables, and I forgot. Normally, if I know that x contains "$$lv.line" and a listview is at line 24, say $x will give me 24. Sorry, I was being dim there.
