/*** Operator and Command Jump Table
* * This file is included by cmd.c and contains the operator and command jump * table. Every command and operator has an entry in the table. The correct * entry in the table can be found in two ways. The first way is to loop * through the table and search for the operator or command name you want. * The second way is to use the xxxTYP variables which are defined in cmd.h. * (xxx is an abbreviation of the name of the operator/command you want.) * These variables can be used as indexes into the table. * */
/* Each entry in the table is made up of one of the following structures.
* The fields are: * name - the name of the operator/command * func - the function which executes the operator/command or NULL if ignore * flags - bit 0 == 1 if the drives of the arguments should be checked */

* The letter "e" has been prepended to all of the function names to keep the * names from conflicting with the names of library routines and keywords. */
