Declare an array type - baltasarq - 11-22-2024

How do you declare an array type? I supposed it should be easy to find in the docs, but didn't have any luck. For instance:

Code:
sub doThis(v as string?)

    print( v( 0 ) )

endsub

I'm certain it is not string() (I have tried that). I wonder if I have to use DIM again?
Thanks,

I think you mean passing an array as a parameter.
This is indeed a bit hidden in the docs: https://zxbasic.readthedocs.io/en/docs/byref/

The syntax is

Code:
Sub doThis(v() as String)

  ...

End Sub

Note that v() can be ANY array of strings of ANY dimensions. You'll have to use LBOUND and UBOUND to retrieve the dimensions of the array if you are expecting arrays of different dimensions.
