I'm dusting off my Atari ST 520, and am trying to understand some semantic details of the GFA basic. The TYPE(ptr)
function is documented this way :
Determines the type of the variable at which a pointer is set.
'ptr' is an integer expression (usually *var).
TYPE(ptr) returns a code according to the type of
variable to which 'ptr' is pointing.
0=var
1=var$
2=var%
3=var!
4=var()
5=var$()
6=var%()
7=var!()
The same documentation does not talk about what these suffixes mean. (It must be so obvious)
I seem to recall that $
is a string/memory block, %
an integer, ()
an array of the same. What are !
and nothing? !
seems to be used for 0/1 variables.
That's correct $ string, % integer, ! boolean , and nothing (0) is double.
