Rem    NAME
Rem      awrmacro.sql - AWR utility to define macros for SQL*Plus scripts
Rem
Rem    DESCRIPTION
Rem      Utility that defines macros to be used in SQL*Plus scripts.
Rem      Macros are implemented as substitution variables. The caller needs
Rem      to pass 2 required arguments, followed by any number of optional
Rem      arguments. The two required arguments are:
Rem        Argument 1: The macro name
Rem        Argument 2: The macro type
Rem        Argument 3-n: Optional arguments specific to the macro type
Rem
Rem      Currently supported macro types:
Rem        - SDM_TYPE: System Data Mask Type
Rem          Expects three additional arguments:
Rem           + scope of masking (MASK_IWD means mask only instance wide data
Rem                               MASK_ALL means mask all data)
Rem           + table alias
Rem           + column name

Rem    NOTES
