This document explains the SQL functions and SQL tables which are
available for the user customization in Free Hero Mesh. (You cannot
use SQL to define the rules of the game.)


=== Functions ===

Asterisks denote aggregate/window functions.

BASENAME()
  The base name, which is a copy of the first command-line argument (not
  counting the switches or the program name).






CLASS_DATA(id,info)
  Returns data about a class.

CVALUE(number)
  Makes a game value of type 'class', given the class number. You can also
  specify the class name instead of the number.

BASENAME()
  The base name, which is a copy of the first command-line argument (not
  counting the switches or the program name).

CL(text)
  Returns the class number, given the class name. If there is no such
  class, then the result is null. (This may be useful as a shortcut when
  used with the "OBJECTS" or "CLASSES" table.)

CLASS_DATA(id,info)
  Returns data about a class.

CVALUE(number)
  Makes a game value of type 'class', given the class number. You can also
  specify the class name instead of the number.
