Was playing around with a dialog to control the colours in the nick list pane of a channel window, and found something strange.

I was laying out the text in the dialog to show the user class, symbol and a dropdown list of colours, and found that the & ($chr(38) for AOPs) character would not display - I got a space instead. Tried it as a text character and also as $chr without any luck. Examining the control (#10) via //echo -st $did($dname, 10).txt did display that the '&' character was still there.
Example code:

Code:

text "&", 10, 48 36 8 10

By chance (read desperation) I decided to try the following.

Code:

text "&&", 10, 48 36 8 10

and it did display a single '&' character

Is this a bug(ette) or something I missed in the help files and wikichip ?

Dialog code for information:

Code:

; Nick Coulours (NC) Preferences dialogue
dialog NCPrefernces {
  title "Nick Colour Preferences"
  size -1 -1 124 168
  option dbu
  text "Class", 1, 12 6 90 10
  text "Symbol", 2, 42 6 18 10
  text "Colour"3, 76 6 20 10

  text "Owner Colour", 6, 4 20 40 10
  text "~", 7, 48 20 8 10 
  combo  8, 66 20 50 11, drop

  text "AOP Colour", 9, 4 36 40 10
  ; text $chr(38) $+ $chr(38), 10, 48 36 8 10 
  text "&&", 10, 48 36 8 10 
  combo  11, 66 36 50 11, drop

The & usage is actually shown in the help file with the example for creating menu, but it's not described at all. Wikichip didn't have anything about it, I added mIRC's example here: https://en.wikichip.org/wiki/mirc/dialogs#Mnemonic #mircscripting @ irc.swiftirc.net == the best mIRC help channel
