Jacque, et al:
* My primary constant list is, in effect, an index to lines of text
in a file and/or variable. It is there to facilitate handler
readability, comprehension, and debugging.
constant badInputWarning = 244
tells me a lot more than
It's kind of like referencing a field by name instead of id or ordinal.
* My secondary constant list is used to facilitate handler modification:
constant simpleSearchIcon = 103405
if the icon of button "Search Type" is simpleSearchIcon then ...
The idea here is, if I should later change the simple search icon to
103450, I could make one change here and need modify nothing else.
Of course, without global constants this doesn't hold true; but at
least I only have to modify one constant declaration at the beginning
of each script rather than searching for every instance of the icon
number in every handler.
* An ancillary use of constants is to support multi-lingual,
constant saveStackMenuItem = 133
constant newStackMenuItem = 107
constant copyStackMenuItem = 206
constant unsupportedChoiceWarning = 2
constant tryAgainPrompt = 202
constant forgetItPrompt = 203
on menuPick thePick
put sdbMessage(saveStackMenuItem) into saveMe
put sdbMessage(newStackMenuItem) into makeMe
put sdbMessage(copyStackMenuItem) into copyMe
put sdbMessage(forgetItPrompt) into quitNow
answer sdbMessage(unsupportedChoiceWarning) with \
quitNow or sdbMessage(tryAgainPrompt)
if it is quitNow then exit to top
