how do you determine the length of an array?

[wizardlife]

Having the subroutine be able to determine the array's properties makes the subroutine more self-contained and possibly more adaptive to being used generically.

True, for something like a general sort or whatever...

[Agamemnus]

pass the reference not the number.

And what does *that* have to do with anything?

What happens if your array is dimmed dynamically or randomly? (Don't ask me when this would happen)

What happens if your array is dimmed dynamically or randomly? What about momoguru? Why do you need to know the number of indexes? (Give me help!)

For the number of indices (yes, that's the REAL plural word for it) you can just make it more dynamic. Say you have a screen buffer, but you make the lib so it can be different lengths. Then you have a buffer filling routine that loops through the array and puts the color numbers. You use UBOUND to get to the end of the array without recoding each buffer size.

Oh and, it is possible to get PUT color values. From Nexus13:

' Determine color value
' ---------------------
IF colour < 128 THEN
c = colour * 257 'Calc fill value if attribute < 128
ELSE
c = colour * 257 - 65536 'Calc fill value if attribute > 127
END IF

' Fill page using color
' ---------------------
max = UBOUND(array, 1) 'Determine maximum words to set
FOR i = 6 TO max 'Set all words starting at element 6
array(i) = c 'Store calculated fill value
NEXT

[Agamemnus]

You wouldn't understand...

As far as I know, LBOUND and UBOUND still work with them.

[Agamemnus]

you can still keep track with random/dynamic arrays.

I'd only use those things if it would otherwise be real complicated to track down teh length.

Glad to see it could possibly be some use to someone. I'll call it "Oracle's Function"
