WWIV ACS Language Proposal

WWIV ACS System

===============

This is a proposal to add an ACS system to WWIV similar to Telegard/Renegade and MysticBBS. The Access Control System (ACS) is specified as a string expression using attributes and operators that can return a boolean yes or no answer. This will replace the existing ACS system of asking or a combination of (SL and DSL and AR, and DAR)

Here are some example expressions:

• "SL=100 & AR=A"
• "SL>=100|AR=A"
• "SL>=50 | R != M"
• "(SL >= 50 & DSL >= 50) | AR=A"

Attributes

Attribute	Description
SL	Security Level
DSL	Downloads DL
RESTRICT	Restrictions
AR	AR
DAR	DAR
AGE	User's Age
USER	User #

Operators

^	true
%	false

!=	not equals
<	less than
<=	less than or equals

|greater than = |g reater than or equals ( |start group ) |end group
