Frequently when a scalar is assigned in a loop that is optimized,
KAP uses a temporary variable within the optimized loop and assigns
the last value to the original scalar if KAP believes that the
scalar may be reused before it is assigned again. The C*$*
assert nolast value needed assertion lets KAP assume that
such last-value assignments are unnecessary. This assertion is
active until reset or until the end of the program.
The /assume=l command qualifiers acts like a global
C*$* assert last value needed assertion.
At /optimize=2 and higher, KAP performs variable
lifetime analysis to determine when last-value assignments are
unnecessary. The C*$* assert nolast value needed
assertion can be used on a loop-by-loop basis when you do not want
to eliminate last-value assignments globally.
