LBOUND

LBOUND function would be useful for determining lower bound of OPTION BASE arrays.

LBOUND function would be useful for determining lower bound of OPTION BASE arrays.

Never mind ... The non-existent BCX "LBOUND" would always be ZERO no matter what the OPTION BASE may be set to.

Gawd, sometimes I feel so stupid!

Code: [Select]


DIM str1$

OPTION BASE 20

GLOBAL MyStrings$[10]
PRINT UBOUND(MyStrings)

MyStrings$[0] = "A BIG FAT ZERO"

PRINT MyStrings$[0]


Results:

Code: [Select]


 29
A BIG FAT ZERO

I never use it but I think the main value is in setting it to OPTION BASE 1, so that your
array gets one more cell and you get to think in terms of 1 to 10 instep of 0 to 9 ... to wit:

Code: [Select]


option base 1
dim i
dim stuff[10]   ' create 11 cells ... 0 to 10

for i = 1 to 10
  stuff[i] = i
next
