|
|
; This needs to be compiled with a specialized patch on Macro32 to make it |
|
|
; preserve the case of symbols instead of converting it to uppercase. |
|
|
; |
|
|
; This patched Macro32 requires all directives to be in upper case. |
|
|
; |
|
|
; There are three sets of |
|
|
; |
|
|
; The first for upper case which matches the tradition method of generating |
|
|
; VAX transfer vectors. |
|
|
; |
|
|
; The second is the exact case for compatibility with open source C programs |
|
|
; that expect exact case symbols in images. These are separated because a |
|
|
; previous kit had only upper case symbols. |
|
|
; |
|
|
; The third is the routine stub that is used to resolve part of the upper |
|
|
; case transfer vectors, with exact case entry symbols. |
|
|
; |
|
|
; When you add routines, you need to add them after the second set of |
|
|
; vectors for both upper and exact case, and then additional entry points |
|
|
; in upper case added to stub routines. |
