PSC Module: Defaults File
 
This file lists all default parameters that appear on the
DEFAULTS tab of the PSC dialog box.  You may add your
own default parameters to this list and they will automatically
be inserted onto this tab.
 
INSTRUCTIONS
 
The following rules must be adhered to when adding (or deleting)
parameters to/from this list.
 
HEADINGS
 
The headings in this file correspond to the six frame blocks that
are on the DEFAULTS tab.  The format of each frame heading is:
                   !n  xxxxxxx
where "!" signifies that this record is a heading, "n" is the
number of default parameters in the frame and "xxxxx.." is the
frame description (with a maximum of 45 characters).  If you
wish to add a default parameter to one of the six frames on this
tab (or delete a parameter) then the value of 'n' must be
increased (or decreased) by 1.
 
PARAMETER & VALUES
 
Lines following the frame heading are assumed to represent a
default parameter and have the following format:
 
"Default variable name, Description, Default value, Units,"
 
(a)  Variable Name
 
This has the form:  "DEF_xxxxxxx" where "xxxxxxx" represents
the name of an existing (base) parameter.  It must have already
been defined in the Parameters List and must appear on at
least one of the tabs in the module.  It can only have a max-
imum of 8 characters.  If "xxxxxxxx" is not a valid parameter it
will be ignored when the "Clear All" button on the Job ID tab is
clicked.
 
(b)  Description
 
The parameter description must not exceed the width of the
frame.  Note again that if you add a default parameter to one of
the six frames on this tab (or delete a parameter) then the value
of 'n' in the corresponding frame heading must be increased or
decreased by 1.
 
(c)  Default Value
 
Default values entered into the dialog box are displayed as text
strings (not numbers).  Consequently, any number of decimal
places may be entered.  For example, if you enter a value of
30.4567 it will be stored internally as “30.4567” and will be
displayed as such when the defaults tab is next opened.  How-
ever, when the default values are inserted into their
corresponding base parameters, they will be displayed and
stored with the number of decimal places relevant to that
parameter as defined in the Parameters List.
 
NOTES:
 
(1) The number of parameter lines following a frame heading
     must be the same as indicated by the "!n .." symbol for that
     heading.
 
(2) The first two frame headings and the defaults immediately
     following them on the defaults file are located in the left-
     hand column of the DEFAULTS tab.  Frames three and four
     are in the middle column and frames five and six in the
     right-hand column.
