Arrays to
store data Part #2 by Charles Carroll
Assigning an array size with a variable
produces a variable unless the Redim command is used.
- Method #1: You know the size
- Method #2: the size is in a variable

dim a_array(100)
' this code will fail

There are many worthy charities!!. But perhaps help starving children in Africa or South America AND help Charles too.
a $5 tip buys him lunch at McDonalds,
a $20 tip buys his kid Hitoshi a new computer game,
a $39 tip buys his daughter Michiko a few nice outfits.
See our donor list.
