A procedure preamble has declarations for parameters and Local variables, Micros, and Macros. Global variables and Structures are declared in a Class preamble. A common format is used when declaring a parameter, variable, or fields within a structure.

Declaration := ['@' | '*'] Name  [Array.Range]  ['='  Static]  [Type ['|' ...]]
             | Name '|=' Static
             | Name [Macro.Parameter]  '=>'  Expression  [Comparator Expression]

Array.Range := '[' Dimension ',' ... ']'

Dimension   := [Lower.Bound  'to']  Upper.Bound

Lower.Bound := Integer.Constant | Enumeration.Value

Upper.Bound := Lower.Bound | Enumerated.Size | '?'

Enumerated.Size := Enumerated.Type '(' '*' ')'

Macro.Parameter := '(' Name  ['=' Expression]  ',' ... ')'
