CLEAR command

[bartok]

I dony' understand. Look at this code:

Code: (Select All)

'DIM SHARED b%(30) 'if activated, the program doesn't work.

REDIM SHARED b%(30) 'if activated, the program works.

'if both deactivated, the program doesn't work. 

CLEAR

FOR i% = 1 TO 40

    REDIM _PRESERVE b%(i%)

    b%(i%) = i%

NEXT i%



CALL ciao



SUB ciao

    PRINT b%(3)

END SUB

So, if CLEAR completely remove b%(), so that it doesn't exist anymore, why it is however needed REDIM SHARED b%(30) before CLEAR? It seems that CLEAR completely remove b%(), without removing the information that it is SHARED. But how is it possible that an inexistent array could be SHARED?
