JRT Pascal User's Guide version 3.0 NOT FOR SALE -119-
9. Customiz
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.
ABC (note no spaces between letters)
