Command table actions

ALIAS: When followed by the name of another command and optional parameters, allows specification of command aliases.
NOP: Causes the command to be functionless. System displays an "inactive command" message in this case.
PASSTHRU: Causes the command to be passed to the dialog, as though it had not been found in the table.
SELECT: When followed by selection keywords, causes the selected dialog command, program or selection panel to be given control immediately.
SETVERB: Causes the command to be passed to the dialog with the command verb stored separately from the parameters.
Blank (no action): Causes the table entry to be ignored, and scanning to continue (to search for additional entries having the same verb).
Variable name: Begins with an ampersand. Its content may be one of the listed actions. Allows dynamic specification of a command action.
