/*** 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
