Interesting
| Code: |
| say "stem.var" stem.var |
So if a 'variable' has never had a value, then it's not really a variable. It's a litteral.
===
| Code: |
say "stem.var" stem.var
var = "AAA"
say "stem.var" stem.var |
So a compound variable still isn't a variable until it gets a value, though if a part of it gets a value, that bit is a variable
===
| Code: |
say "stem.var" stem.var
var = "AAA"
stem.var = "bbb"
say "stem.var" stem.var
say "stem.AAA" stem.AAA |
And now because the compound variable is given a value, it becomes a variable, but not only that, the part of it that got a value (var) is also a variable, so the compound variable can be refered to using either the variable var or the value of the variable var (AAA).
I wonder if they are the same thing . . .
===
| Code: |
say "stem.var" stem.var
var = "AAA"
stem.var = "bbb"
say "stem.var" stem.var
say "stem.AAA" stem.AAA
stem.AAA = "ccc"
say "stem.var" stem.var
say "stem.AAA" stem.AAA |
stem.var and stem.AAA appear to be the same thing.
...well it's a little confusing 
but then again, it's probably only like saying
| Code: |
WRITE "ARRAY(var)" ARRAY(var)
var = 1
ARRAY(var) = "bbb"
WRITE "ARRAY(var)" ARRAY(var)
WRITE "ARRAY(1)" ARRAY(1)
ARRAY(1) = "ccc"
WRITE "ARRAY(var)" ARRAY(var)
WRITE "ARRAY(1)" ARRAY(1)
