--- Entry for bigintegers made in * KEY_OF_DATAWORD.
Aug 21 (John Gibson)
--- POPLOG Version 11. This has BIGINTEGERS, i.e. arbitrarily large
integers. These work with all the arithmetic functions, and mean
that operations like +, -, *, etc will return bigintegers when
integer computations overflow simple integers. "isbiginteger" tests
for a biginteger, and "isintegral" for an integer or biginteger
("isinteger" still returns true only for a simple integer).
An important change that may affect some programs is that the
logical operations ||, &&, &&~~, ~~, << and >> will now only accept
integers or bigintegers, and in particular, << will produce a
biginteger if overflow occurs. Some uses of these operations (e.g.
to get address values to pass through "external_apply") will no
longer work, and for this reason the old versions of the operators
are available as "fast integer" forms, i.e. fi_&&, fi_||, fi_~~,
fi_<<, fi_>>, etc. There is also a new exclusive-or operation, ||/&
and fi_||/&.

From V11 you can specify the search path for saved images with an
environment variable "popsavepath". This has the same syntax and
meaning as the shell's PATH variable. The default is
":$popsavelib:$poplib" which is the same as it is now. See HELP *
PARAMETERS. The search path for a file to compile is given
similarily by "popcomppath".
