If
flag
is non-nil, the top generation is collected; if
flag
is any other value, the top generation is not collected. The default is
nil
.
The function
collect-highest-generation
controls whether the top generation is garbage-collected in 32-bit LispWorks.
collect-highest-generation
is implemented only in 32-bit LispWorks. It is not relevant to the Memory Management API in 64-bit implementations.
