With ACS codes a SysOp is able to gain complete control over what a user
 can do, this may sound communistic or overbearing but look at it this way,
 you wont have to worry too much about someone hacking into the board. With
 full ASC code capability and if your expressions are complete they still wont
 have that many more options that can be damaging to the system. When you
 weigh the benefits of these ACS codes, you'll find that your users will
 actually like them, because it means that your thorough and your system will
 be up longer because no one has any back door capabilities, unlike some other
 systems. There are several codes that can be used, each with it's own
 particular use, and when you combine these into large expressions it tends
 to make things more secure. Each ACS code is explained below in as much
 detail as I can muster.


   =         True if the user is in local mode. This allows for a SysOp to    
             secure certain areas from over the modem use, preventing users
             from using commands which may or may not be dangerous to the
             system.

   *         True if OkFlag (See Miscellaneous Menu Commands) is set, if the  
             OkFlag has been left unset, this command will return false and
             will continue to the next command set, ignoring all information
             of the current command set, unless otherwise stated.

   Axx       A user must be 'xx' years or older in order for this ACS code to 
             be true, if it returns false, then it will continue on to the
             next command set, ignoring all information in the current
             command set, unless otherwise stated.

   Bxxxxx    A user must be connected at 'xxxxx' baud or faster in order for
             this ACS code to be true, if it returns false, then it will      
             continue on to the next command set, ignoring all information in 
             the current command set, unless otherwise stated. This ACS code  
             will also return true when in local mode.

   Cx        A user must be in message conference 'x' in order for this to
             return a true response, when it returns a false response it will 
             ignore all information in the current command set and move on to 
             the next command set.

   Dxxx      A user must have a Download Security Level (DSL) of 'xxx' or     
             greater to return a true response, if it returns a false
             response it will ignore all information regarding the current
             command set and move on to the next command set.

   Fx        A user must have the access flag 'x' toggled on in order for     
             this ACS code to return true, if a user doesn't have the access  
             flag 'x' toggled on, Iniquity will ignore all remaining
             information regarding the current command set and continue on
             to the next command set.

   Gx        A user must be of gender 'x' (M = Male, F = Female) in order for
             the ACS code to return true, if false Iniquity will move on to
             the next command set, ignoring all information in the current
             command set.

   Hxx       If the hour is 'xx' (xx = 0 to 23) or later, then the ACS        
             command will return true, if the ACS command returns false it
             will ignore all remaining information in the current command set,
             and move on to the next command set.

   Kxxx      If a user's area code is 'xxx' then this ACS command will return
             true.

   Nxx       If a user is on this node the command can be executed.

   Pxxxx     A users number of posts must be at least 'xxxx' in order for the
             ACS code to return true, if false it will ignore all remaining   
             information in the current command set, and move on to the next  
             command set.

   Sxxx      If a user has a security level (SL) of 'xx' or greater then the  
             ACS code will return true, if false then all remaining
             information will be ignored in the current command set, and
             Iniquity will move on to the next command set.

   Txxxx     If a user has at least 'xxxx' minutes left online then the ACS   
             code will return true, if the user doesn't have 'xxxx' minutes
             left online, then the ACS code will return false and Iniquity
             will ignore all remaining information and move on to the next
             command set.

   Uxxxx     If the user is number 'xxxx', then the ACS code will return      
             true, if false then all remaining information will be ignored by 
             Iniquity and Iniquity will move onto the next command set.

   V         If a user has a validation level of 'B' or greater, the this ACS
             code will return true, when false all remaining information will 
             be ignored, and Iniquity will move onto the next command set.

   Wx        If the current day of the week is equal to 'x' (x = 0 to 6,      
             Sunday is 0), then the ACS code will return true, if it returns  
             false Iniquity will ignore all remaining information in the
             current command set, and continue on to the next command set.

   Xx        A user must be in file conference 'x' in order for the ACS code  
             to return true, when it returns a false response it will ignore
             all information in the current command set and move on to the
             next command set.

   Yxxxx     At least 'xxxx' minutes from midnight has to have passed in      
             order for this to be true, if Iniquity returns a false response  
             then all information in the current command set will be ignored, 
             and Iniquity will move onto the next command set.



   Z         To be true, a user's post/call ratio must be greater then or     
             equal to his/her security level requirements, if Iniquity returns 
             a false response all information in the current command set will 
             be ignored and Iniquity will move on to the next command set.

   Iniquity's access condition parser allows logical statements much like
   those found in many popular programming languages. The following logical
   operators may be used when using ACS expressions:

     !     This Logical NOT will inverse any expression that follows the        
           operator, if the expression would normally have returned true, it
           will now return false.

     &     This Logical AND is used to combine two expression, thus making two  
           requirements needing to be true, not just one.

     |     This Logical OR creates an expression that uses either side of the   
           operator. If one side or the other returns true, then the expression 
           is true.

     ( )   These operators can be used to group sets of expression creating a   
           complex ACS expression, if the entire expression has a return values 
           of true, then execution is continued for the current command set, if 
           the overall result of the expression returns false then all is
           ignored for the current command set and Iniquity moves on to the next
           command set.

         The following is a couple of examples for ACS expressions that can be
     used in most situations:


     S100|(S50&A18)    Requires that either the user has an SL of at least 100  
                       or that the user has an SL of at least 50 and is at
                       least 18 years of age.

     !s51|(u1&=)       Requires that the user has an SL of 50 or LESS, or that  
                       he/she is logged on from the local console as user number 
                       1 (Usually the SysOp).
