;
; RENAME Command --
; RENAME is used to change the name of one or more files. Unlike
; the ZCPR2-resident REN function, RENAME permits ambiguous file names
; and supports an Inspect mode that allows the user to confirm each
; rename before it is done. Additionally, there is a Control Mode which
; allows the user to manually specify the name for each file as it is
; presented to him.
;
; The RENAME command may be of the following forms:
; RENAME dir:afn1=afn2,dir:afn3=afn4,... o
; RENAME dir:afn,dir:afn1=afn2,... o
; The first form shows elements of the form
; dir:afn1=afn2
; while the second form shows elements of the form
; dir:afn
; which is the same as
; dir:afn=afn
; and only makes sense if Control Mode is used.
;
; The option characters (o) are none or more of the following:
; C -- Control Mode; manually specify each new name
; I -- Inspect and approve each rename
; S -- Include SYStem files
;
; Examples:
; RENAME *.MAC=*.ASM <-- Rename all ASM files to MAC
; RENAME *.MAC C <-- Rename all MAC files to names
; input by the user
; RENAME *.OBJ=*.COM SI <-- Rename all COM files to OBJ
; and include SYStem files
; and Inspect and approve each
; change
;
