Undefined element of (assoc) array shown as 'string'

[PeterH]

I'd expect vartype() to show an undefined element of an (associative) array as 'undefined'.
But it's shown as 'string'. To repro (see following script):

- Array $GAf[] is undefined
- Define it by setting one element "c" to 0
- now check any other (non-existing) element by VarType(): it's shown as "string"
- (should be "undefined", I think)

- set a yet undefiined element to 3
- VarType() now shows it correct as "int".

Result: an undefined element can't be recognized!

(Sample script, made from a real world script. There the array is Global - but that makes no difference.)

Code: Select all

//§
"Test"
   step;
   $GAf["c"] = 0;                   // define $GAf[] by setting 1 element
   $exist  = VarType($GAf["abc"]);  // is undefined, but shown as "string"
   $exist  = VarType($GAf[11]);     // is undefined, also shown as "string"

   $GAf["abc"] = 3;                 // define it by setting to 3
   $exist  = VarType($GAf["abc"]);  // now correct shown as "int"

Agreed! Next beta.

Prev was for implementing, now a for testing.

Is it so that I alone found > 80% of bugs with arrays?

Looks like it, arrayzor head!
