YOU WERE A HC USER??!!??
Sorry. Ahem.
But then you must remember that you cannot add "$50" to "15". xTalks are
typeless, and the parser resolves strings into usable form purely by context.
So you can only add strings that resolve to numbers.
Would this be immediately understandable to you?:
function goodNumber tText --valid in both HC and LC
repeat with y = 1 to the number of chars of tText
if char y of tText is in ".0123456789" then put char y of tText after temp
end repeat
return temp
end goodNumber
In LC, we have another way to do it:
function goodNumber tText --valid in LC only
repeat for each char tChar in tText
if tChar is in ".0123456789" then put tChar after temp
end repeat
return temp
end goodNumber
This last is faster; LC is a superset of HC. But you must already have a huge
head start in all this. It is just a matter of learning new language elements,
unlearning such things as backgrounds in lieu of groups, and so forth. An
effort, to be sure, but I retract my wager. You already have won, though it
appears you do not yet know it.
Were you part of the HC community 15 years or so ago? The LC one is larger,
comprised of many of the same (now older) members, and growing. Thank heaven.
