SET^FILE Procedure
•
The ASSIGN^SECEXT operation comes into effect only when an
ASSIGN^PRIEXT (or ASSIGN^PRIMARYEXTENTSIZE) operation is specified. If
the primary extent (ASSIGN^PRIEXT) has not been set explicitly, any command to
set the secondary extent (ASSIGN^SECEXT) will be ignored, and the secondary
extent will have the default value. The following table describes operations that set
values in the
new-value parameter.
