Searching an Executable Library Not Specified at Load Time 

HPGETPROCPLABEL can search for procname in one XL not specified at load
time.  The XL must be specified in firstfile, and any unresolved external
references within the XL must be resolved only in the System Libraries.
If firstfile is not found in the libraries available to the process, the
XL is placed in a binding sequence independent of the original binding
sequence prior to the dynamic loading of procname.  The dynamically added
library contains supplemental code that can only be executed via a
dynamic procedure call.

Figure 3.2 shows a program loading using two user XLs and the System
Library.  Also, the process has dynamically loaded a procedure located in
an XL not specified at load time.  The original binding sequence of the
process is not altered.
