You can do this with a global variable, but I too would be interested in
knowing if Rebol has directly implemented this for variables local to a
function, but I think I've figured out the answer (or at least a
work-around). Declaring a local variable to a block (without using make
block!) will retain the value to that block. So, you can keep all of your
static data within that block.
f: func [][
static: [0]
either zero? static/1 [
change at static 1 1
print "Function called first time"
][
print "Function called the next time"
]
]

Subject: [REBOL] "static" variable
Hi,
Does anyone know whether Rebol has such a kind of variable: you initialize
this
variable at the first time you run the script. In this script, the variable
will
be modified to some value. If you run this script again, this variable will
preserve the value it has in last run.
Thanks in advance.
