The binding sequence is a list of XLs the loader searches
to satisfy your program's unresolved external references. The loader
creates the binding sequence at load time.
The program file is placed first in the binding sequence.
Any additional XLs are placed after the program file in the
order in which you specified them. The System Libraries (XL.PUB.SYS
followed by NL.PUB.SYS) are always placed last in the binding sequence.
The order of the binding sequence is important, as the loader
makes a single pass in one direction through the list.
MPE XL enables you to specify additional XLs you want placed in
the binding sequence by using any of the methods described in
groups one through three below.
An XL list specified using methods described in group two always
override lists specified using methods described in group one.
Likewise, lists specified using methods described in group three
always override lists specified using methods
described in groups one and two.
You can specify a list of your own executable libraries in
the XL= parameter of the :LINK command.
You can specify a list of MPE XL-defined libraries in either
the LIB= parameter of the :RUN command or the
flags parameter LIBSEARCH bits of the CREATE or
CREATEPROCESS intrinsic.
You can specify a list of your own executable libraries in
the XL= parameter of the :RUN command, or Item Number 19 of the
CREATEPROCESS intrinsic.
For example, if the calling process was created with the
following command:
:$$RUN PROGRAM1; XL=LIBA,LIBB,LIBC,LIBD
