public variables, scope, local variables, and function calls

[Charles Pegge]

In o2, redim is  really a macro for creating and resizing dynamic arrays, whereas dim can only create fixed-size arrays and other variables.

You can repeatedly redim an array to resize it, and the original data will be preserved.

Charles,
in case I want to resize an array that has been declared publicly

Code Select Expand


dim int ArrayK[100]

sub aa()
int t=50
  redim  int ArrayK[t]
   ArrayK (20) = 100
  print ArrayK (20)
end sub

call  aa

print ArrayK (20)

You can make your initial redim with 0 elements, if you prefer. But it must be a redim

Code Select Expand


redim int ArrayK[0]

sub aa()
int t=50
  redim  int ArrayK[t]
   ArrayK (20) = 100
  print ArrayK (20)
end sub

aa()

print ArrayK (20)

Thanks, Charles.
it's one more thing to go for help and for the manual
