.. known an way to test if index of associative array is defined?...

Code: Select all

? HB_HPOS( hMyHash, 'NotFoundIndex')  // --> 0

You can found details here.

I tried to use associative array to translate logical vaue:

Code: Select all

 aYesNo := {=>}
 aYesNo[ .f. ] := "No"
 aYesNo[ .t. ] := "Yes"
 

I got an compiler error.
Logical keys are not allowed? Am I right? Has abybody more experiences with this?

Hi Mol,
I think you need to search in harbour sources/samples for hb_hash()

Code: Select all

to define  hash:

myHash := { "item1"=> .T. ,;
                   "item2" => 1234 ,;
                   "item3" => date() }

setting another value

myHash[ "item1" ] := .F.

Thanks Marek, you are right

Has been made correction in VivaClipper page :

Typing :

<key> part of a hash may be any legal scalar type : C, D, L, N ...

Correction : This definition is wrong ! The correct is :

<key> entry key; can be of type: number, date, datetime, string, pointer.

Corrected at : 2015.12.08; thanks to Marek.
