Done DO x in /A(rray) array_name ...

[vefatica]

I've been using arrays a lot and I'm tired of typing

do i=0 to %@dec[%@arrayinfo[array_name,1]]

and later having to refer to %array_name[%i].

[And I don't know if you can overload "/A".]

But it would be very convenient to be able to process a 1-D array like this.

do x in /A array_name ...

and later refer to %x.

I think just

DO x IN %[array]
…
ENDDO

should work.
Or add @ARRAY[] variable function for that purpose.

How about:

rem  Any array:
DO x IN AROWS arrayname

rem  Array with at least two dimensions:
DO x IN ACOLS arrayname

This is all just syntax sugar. It doesn't have to be implemented by Rex. A plugin can massage command parameters. Or you could write an alias or two.

How would that work?

1-D would be fine with me and I suspect relatively easy compared to that one. If /A(rray) isn't available, I like /V(ector); after all a vector is a 1xN array.

Naturally. I don't quite understand your confusion.

It doesn't.

v:\> setarray a[10] & do i=0 to 9 (set a[%i]=%i)

v:\> do x in %[a] echo %x
Usage : DO [n | FOREVER]

And I wouldn't expect it to work. "%[a]" is a reference to the environment variable whose name is "a".

v:\> set a=2

v:\> echo %[a]
2

What would @ARRAY[] do?

 

[AnrDaemon]

%@ARRAY[name] would convert the array variable into a list of its outer dimension values.
