Believe it or not, when field “display” contains “0.”, the following evaluates
to TRUE:
if (space & fld “display”) = (space & “0”) then … # TRUE!
And even:
if (space & fld "display" & space) = (space & "0" & space) then … # TRUE
AGAIN!
It’s the space that’s the problem. Any other character seems to do the trick:
if ("!" & fld "display") = ("!" & "0”) then … # FALSE
Try explaining that to newbies. “Oh, I’m just coercing LiveCode to cast the
field contents as a string instead of a number.”
Blank stares and crickets… :)
