Having just begun porting an application to VMS on the Alpha, I have
a question concerning the format of the SYMBOL_VECTOR command in
a linker options file. Of course, I don't have the new linker manual.
I realize that one now replaces macro-coded transfer vectors by
linker options of the form:

	SYMBOL_VECTOR=(routine1=PROCEDURE,routine2=PROCEDURE,...)

etc. What other values are accepted in place of PROCEDURE? For
example, I have a VAX/VMS shareable image that defines a couple of hundred
universal message symbols (ie created in a .MSG file and linked in
with the shareable image). In the linker options file, I have:

	UNIVERSAL=PROG__MSG1
	UNIVERSAL=PROG__MSG2, etc.

What is the appropriate form of SYMBOL_VECTOR command to replace this?
Thanks, one and all.

Steve

Steve,
	The SYMBOL_VECTOR linker option has multiple incarnations.. where
in general it is described as:

SYMBOL_VECTOR=([[alias_name/]symbol-name=]symbol-vector-entry-type)

symbol-vector-entry-type may be any of:

DATA		  - symbol vector for data cell
PRIVATE_PROCEDURE - creates enty for a routine that is not propageted to the 
		    GST of the shareable image
PRIVATE_DATA 	  - same as above except is for data
PROCEDURE 	  - vector entry for a routine entry
PSECT		  - create entry for a program section
SPARE		  - reserve space for a future entry

Notice that DEC also allowed for aliasing of symbol names.. I believe for the
replacement of what you have you want..

SYMBOL_VECTOR=(PROG__MSG1=DATA)
SYMBOL_VECTOR=(PROG__MSG2=DATA)
