sure this is something to do with me not learning the basics properly. ive taken out all parts of code relevant:

why is it that...

dim model_paths$(1)
model_paths$(1) = "models\patrolboat_v1.1.x"

dim units#(max_units,15)
unit_class as integer : unit_class = 2
pboat as integer : pboat = 1

units#(1,unit_class) = pboat
load object model_paths$(units#(1,unit_class)),1

...will return garbage as the string whereas...

dim model_paths$(1)
model_paths$(1) = "models\patrolboat_v1.1.x"

dim units#(max_units,15)
unit_class as integer : unit_class = 2
pboat as integer : pboat = 1

units#(1,unit_class) = pboat
path = units#(1,unit_class)
load object model_paths$(path),1

....will work fine?

maybe i cant lookup an array based on the value of another one?

No, the problem is you can't refence an array using float variables, only integers.

i.e. this is ok:

a=1
print xyz$(a)

but this is not:

a#=1
print xyz$(a#)

Does 'unit' array need to hold float values. If not, the change from 'unit#' to 'unit'

Boo!

Yeah ... what he said

Change this line:

load object model_paths$(units#(1,unit_class)),1

To this:

load object model_paths$(int(units#(1,unit_class))),1

Or better still, if you can, remove the need for the Units array to be floating point. There doesn't seem to be a need for floating-point here.
