Hello -

Since we're on the subject of save/restore, there is a little problem
with boRecord.c that forces us to restore soft BOs differently from
soft AOs.  For both record types, we set DOL to blank (these are soft records 
and are used for storing constants and user inputs).  We then use use static 
db restore in initHooks.c before record initialization to restore VALs from 
file.  I need to set PINI to YES on the soft BOs in order to get the proper 
severity to drive the color on some displays (usually RED if OFF and GREEN if 
ON).  However, for a soft BO with a blank DOL, process won't reset the udf flag 
to true and the severity is INVALID until somebody does a ca put to change
VAL.  So I'm forced to restore soft BOs with channel access after initHooks
is done.  I don't have the problem with soft AOs since process (convert, really)
will always set udf to false no matter what.  

Could the process function of the boRecord.c be changed:

                /* convert val to rval */
                if ( pbo->mask != 0 ) {
                        if(pbo->val==0) pbo->rval = 0;
                        else pbo->rval = pbo->mask;
                } else pbo->rval = (unsigned long)pbo->val;
>>>add this>>>  pbo->udf = FALSE;

Thanks,

Stephanie
