I know of no function in modern JAWS for classifying the contents of a
variable. However, I do know a few tricks, so here's my shot at a
TypeOf function off the top of my head. Warning: I didn't even try to
compile this.
string function typeOf(variant x)
; Return the JAWS type name that seems best to describe the content of x.
; Types returned: int, object, string.
; Handle and int are indistinguishable, so handles are not identified here.
; Empty (never assigned) values will return string.
; Objects with default properties may return incorrect results.
if x then
if !stringLength(x) then
; An object is the only thing that's boolean True but with 0
string length.
return "object"
elif stringToInt(x) && stringLength(x) ==
stringLength(intToString(stringToInt(x))) then
return "int"
else
return "string"
endIf
else ; x is boolean False
if stringLength(x) then
; Integer 0 is all that can do that one.
return "int"
else
; This may catch more than we want, but it should be close.
return "string"
endIf
endIf
endFunction

Hello,
I'm using the latest build of JAWS 13 under Windows 7.
Does anyone know if there is a JAWS function for confirming if the
value stored in a variable is a number or text string? Sure there is,
but looking through the list of over 250 functions to find it has my
head spinning.
Thanks for any help.
