It's a design feature of REBOL that trips everyone up at first because it is
so unlike most of the other languages we've ever used. I wrote off several
hours once to debugging the same problem.
Even local "variables" have this sort of "persistence" to them. Watch what
these strings do:
a-func: func [data /local var1 var2 var3][
var1: ""
var2: ""
var3: copy ""
append var1 data
append var2 data
append var3 data
print [var1 "--" var2 "--" var3]
]
loop 5 [a-func random/secure "ABCDE"]
One day, you'll thank Carl for this feature,
Sunanda.
