RE: Looking for better coding

Gary,

The question was how is RESET effected by using INZ(*SYS) for a date
field.
And you are correct that RESET sets up the initial values for a field
based on their content at the end of *INZSR. I know, and worked with the
original developer of RESET, CLEAR and data structure initialization.

So yes, if in addition to using INZ(*SYS) on a date field, you also
change the field's value during the *INZSR, the value copied back into
the field by a RESET operation will be the value specified in the
*INZSR.

To the point of the original question, RESET will not regenerate a new
date or time value simply because a date or time field had *SYS as its
default value.
