Hi,
This is my first posting in this newsgroup. So hold your flames if this
is a dumb question.
C allows "register ......" construct which instructs the compiler
to reserve a machine register to store that value. Now my question is,
given a fixed number of registers, How many are effectively usable for
the register declaration. I know this is machine dependent. Could
somebody say how many register definitions I could use within a block
of code say for a VAX. And please go on to mention the CPU/Machine that
allows the greatest number and smallest number of such declarations.
Is this number fixed or does it change as the program runs.
