; <8> 1/30/91 mbs cj,#82011: Move years after company name in copyright message.
|
|
; <7> 12/17/90 mbs The ALIGN directive does not work for the IIGS assembler. Use
|
|
; IF ENDIF to generate an extra dc.b 0 if necessary. Yes except
|
|
; for the ALIGN, the entire macro worked under the IIGS
|
|
; assembler!.
|
|
; <6> 11/28/90 mbs In the VERSION macro, when the release stage is 'released', pad
|
|
; the version with two trailing spaces so that the length remains
|
|
; the same when changing from an f1 to a Golden Master build.
|
|
; <5> 11/26/90 mbs Did not handle 3-digit major version number
|
|
; <4> 11/12/90 mbs Steven pointed out that verUs is zero, not 1.
|
|
; <3> 11/10/90 mbs Add optional parameter to set the label at the front of the
|
|
; version structure.
|
