 B.3.2.1 Compiling `gawk' on VMS
 ...............................
 
 To compile `gawk' under VMS, there is a `DCL' command procedure that
 issues all the necessary `CC' and `LINK' commands. There is also a
-`Makefile' for use with the `MMS' utility.  From the source directory,
-use either:
+`Makefile' for use with the `MMS' and `MMK' utilities.  From the source
+directory, use either:
+
+     $ @[.vms]vmsbuild.com
+
+or:
 
-     $ @[.VMS]VMSBUILD.COM
+     $ MMS/DESCRIPTION=[.vms]descrip.mms gawk
 
 or:
 
-     $ MMS/DESCRIPTION=[.VMS]DESCRIP.MMS GAWK
+     $ MMK/DESCRIPTION=[.vms]descrip.mms gawk
+
+   `MMK' is an open source, free, near-clone of `MMS' and can better
+handle `ODS-5' volumes with upper- and lowercase filenames.  `MMK' is
+available from `https://github.com/endlesssoftware/mmk'.
+
+   With `ODS-5' volumes and extended parsing enabled, the case of the
+target parameter may need to be exact.
 
    Older versions of `gawk' could be built with VAX C or GNU C on
 VAX/VMS, as well as with DEC C, but that is no longer supported.  DEC C
 (also briefly known as "Compaq C" and now known as "HP C," but referred
-to here as "DEC C") is required.  Both `VMSBUILD.COM' and `DESCRIP.MMS'
+to here as "DEC C") is required.  Both `vmsbuild.com' and `descrip.mms'
 contain some obsolete support for the older compilers but are set up to
 use DEC C by default.
 
-   `gawk' has been tested under Alpha/VMS 7.3-1 using Compaq C V6.4,
-and on Alpha/VMS 7.3, Alpha/VMS 7.3-2, and IA64/VMS 8.3.(1)

+The most recent builds used HP C V7.3 on Alpha VMS 8.3 and both Alpha
+and IA64 VMS 8.4 used HP C 7.3.(1)

+B.3.2.2 Compiling `gawk' Dynamic Extensions on VMS
+..................................................
+
+The extensions that have been ported to VMS can be built using one of
+the following commands.
+
+     $ MMS/DESCRIPTION=[.vms]descrip.mms extensions
+
+or:
+
+     $ MMK/DESCRIPTION=[.vms]descrip.mms extensions
+
+   `gawk' uses `AWKLIBPATH' as either an environment variable or a
+logical name to find the dynamic extensions.
+
+   Dynamic extensions need to be compiled with the same compiler
+options for floating point, pointer size, and symbol name handling as
+were used to compile `gawk' itself.  Alpha and Itanium should use IEEE
+floating point.  The pointer size is 32 bits, and the symbol name
+handling should be exact case with CRC shortening for symbols longer
+than 32 bits.
+
+   For Alpha and Itanium:
+
+     /name=(as_is,short)
+     /float=ieee/ieee_mode=denorm_results
+
+   For VAX:
+
+     /name=(as_is,short)
+
+   Compile time macros need to be defined before the first VMS-supplied
+header file is included.
