type var
type[scope][ptr][&] var[(expression)] [var2[(expression)] ...] [= expression]
type - variable type name.
var - variable name.
scope - variable storage and scope. Can be one of symbols listed below. Default: var is local.
| + | var is global variable. |
| - | var is thread variable, shared by all functions of current thread. |
| -- | var is thread variable, private to current function. |
ptr - up to three * characters used to declare pointer variable.
& - declare reference variable.
expression - initial value. Default: 0 or empty.
Creates one or several variables.
For ARRAY variables, also must be specified array type (type of elements): ARRAY(type) var
Member functions can be called inside declaration statement: type var.member(args)
Local variables can be declared inline, using syntax type'var. See example with for.
