Rule Restrictions Recognized by RULEEDIT

The following are valid formats for rule restrictions used by RULEEDIT:

<SimpleCondition>

<Condition> | <Condition>

<Condition> & <Condition>

(<Condition>)

! <Condition>

<SimpleCondtion> ::= <StringCondition> | <NumericCondition>

<StringCondtion> ::= <Tag> ( = | # | } ) <StringLiteral>

<NumericCondition> ::= <Tag> ( # | = | > | < ) <NumLiteral>

<BoolCondition> ::= <Tag> = ( 1 | 0 )

<Tag> ::=<PR_xxxx of a property for a string value> |[ <HexNumber> ]

<NumLiteral> ::= <Decimal Number>

<StringLiteral> ::= <String enclosed in AND>

<HexNumber> ::= <StringOfHexDigits>

where the following rules apply:

• | is logical OR. & is logical AND. ! is logical NOT.
• AND and OR conditions group from left to right. They are always converted to binary operations. For example:

  A | B | C <=> ( A | B ) | C.

• No precedence exists between AND and OR. For example:

  A | B & C | D <=> ( (A | B ) & ) C | D

• The NOT operator always applies to the condition that immediately follows it. For example:

  : ! A | !B & ! ( !C | D ) <=> ( ( ! A ) | ( ! B ) ) & ( ! ( ( ! C ) | D ) )

• = is equal.
• # is not equal.
• a } b is a contains
• b. ::= is assignment

Note Unlike action entries, only one restriction entry may be present in a command section. If a rule is invoked on a complex restriction, the restriction must still be included in a single expression
