; LIBENT - GENERATES POST-MORTEM BLOCK, POINTER TO IT & PARAM CALL
; FOR LIBRARY ROUTINES THAT LOOK LIKE GENUINE ALGOL PROCEDURES
;
; CALL - LIBENT(ALIAS-#,NAME,V)
;
; WHERE: ALIAS-# IS THE 1-,2- OR 3-DIGIT ALIAS NUMBER
; (WHICH AGREES WITH THE LIB MACRO IN ALGCON)
; FROM WHICH THE PROCEDURE'S ENTRY-POINT NAME IS FORMED,
; VIZ: %NNNA FOR KA10 OBJECT OR %NNNI FOR KI10 OR
; OR %NNNK FOR KL10.
;
; NAME IS THE SIXBIT NAME OF THE PROCEDURE:
; THIS IS DUMPED INTO THE POST-MORTEM BLOCK
; FOR THE RUN-TIME TRACE PACKAGE TO TYPE OUT.
;
; V IS OPTIONAL. IF PRESENT, THE PROCEDURE HAS A
; VARIABLE NUMBER OF PARAMETERS (SEE, FOR EXAMPLE, IMAX)
; AND V WILL BE THE OFFSET ON THE LOCAL STACK WHERE PARAM
; WILL STORE THE NUMBER OF ACTUALS.
;
; THE MACRO GENERATES EVERYTHING THAT IS NEEDED FOR PROCEDURE ENTRY,
; EXCEPT FOR THE SEARCH ALGPRM,ALGSYS WHICH MUST PRECEDE IT.
; THE JSP AX,PARAM OR PAR0 IS GENERATED, AND THE P.M. BLOCK
; POINTER, BUT NOT THE DESCRIPTOR-WORDS THAT FOLLOW. ENTRY
; STATEMENTS ARE GENERATED, AND THE NAME IS PUT INTO THE CREF FOR
; EASE OF FINDING THE PROCEDURE IN A LARGE LIBRARY-LISTING.
