/*** ProcessCommands - high-level command processor
|
|
*
|
|
* Purpose:
|
|
* If no command string remains, the user is prompted to
|
|
* input one. Once input, this routine parses the string
|
|
* into commands and their operands. Error checking is done
|
|
* on both commands and operands. Multiple commands may be
|
|
* input by separating them with semicolons. Once a command
|
|
* is parsefd, the appropriate routine (type fnXXXXX) is called
|
|
* to execute the command.
|
|
*
|
|
* Input:
|
|
* g_CurCmd = pointer to the next command in the string
|
|
*
|
|
* Output:
|
|
* None.
|
|
*
|
|
* Exceptions:
|
|
* error exit: SYNTAX - command type or operand error
|
|
* normal exit: termination on 'q' command
|
|
*
