           External  procedures  and functions are compiled separately from
      the main program.  They can be linked together with the main  program
      using  the  Linker  (section 8 of this manual).  If this is not done,
      they will be automatically loaded from disk into the computer's  main
      storage  when  they  are  first  referenced.   If  a short-on-storage
      condition arises, they may be purged from storage  if  they  are  not
      currently active.

           Procedures  which  are rarely used, like initialization or error
      handling, would not occupy main storage except  when  needed.   Also,
      very  large  programs  might  be  divided  into  several phases, each
      corresponding to an external procedure.

           The EXEC loads the external procedures from disk.  There  is  no
      need  to  inform  EXEC on which disk each procedure resides - it will
      search for them.  This means that you do NOT  have  to  put  all  the
      program sections onto the A: disk.

           EXEC  and  the  compiler,  JRTPAS3,  contain 'disk search lists'
      which specify which disks are available on the  system.  The  default
      lists  are  set  to  'AB',  i.e.,  drives A: and B:.  The seach lists
      should be  modified  to  reflect  the  hardware  configuration.   The
      Customiz  program  is  provided  to modify the lists in both EXEC and
      JRTPAS2 simultaneously.  Before running Customiz, be sure  that  both
      EXEC  and  JRTPAS3  are  not  write  protected  files  or  on a write
      proctected disk or drive.  To run Customiz, enter:

                  EXEC CUSTOMIZ


           A new disk search list, with up to four  disk  letters,  may  be
      specified.   The letters must be contiguous. NOTE that this list also
      determines the SEQUENCE in which  the  disks  are  searched  for  the
      external procedures and functions.
