Upper bound of arrays in PB/Win 8.04

[John Harvill]

What is the upper bound for arrays in PB/Win 8.04, when dimensioned simply as follows:

DIM a(20) AS LONG
DIM s(20) AS STRING

I thought that the indexes for these arrays would range from 0 to 19. However, I'm finding a range of 0 to 20 in the following example:

 
#COMPILE EXE
#DIM ALL
 
FUNCTION PBMAIN () AS LONG
    DIM a(20) AS LONG
    DIM s(20)  AS STRING
 
    OPEN "output_TestArray.txt" FOR OUTPUT AS #17
 
    PRINT #17, "ubound_a = "; UBOUND( a(1) )
    PRINT #17, "lbound_a = "; LBOUND( a(1) )
    PRINT #17, "ubound_s = "; UBOUND( s(1) )
    PRINT #17, "lbound_s = "; LBOUND( s(1) )
 
    CLOSE #17
 
END FUNCTION

Sincerely,

0 to 20.
Total = 21 elements.

Its all in the help file.

You can use this:

DIM s( 1 to 20) AS STRING

or...

DIM s(0 to 19) AS STRING

Thanks,

You're absolutely right. There it is in clear black and white.
