GetMem
and FreeMem
are supported like in BP.
The second parameter to FreeMem
is ignored by GNU Pascal and
may be omitted. Memory blocks are always freed with the same size
they were allocated with.
Remark: Extended Pascal Schema types provide a cleaner approach to
most of the applications of GetMem
and FreeMem
.
Min
and Max
: GNU Pascal has built-in Min
and
Max
functions (two arguments) which work for all ordinal
types (Integer
, Char
, ...) plus Real
.
UpCase
, High
, Low
and similar functions are
built-in. In contrast to Borland Pascal, GNU Pascal's UpCase
function is aware of non-ASCII characters of certain languages
(e.g., accented letters and “umlauts”), but for compatibility this
feature is disables in --borland-pascal
mode. There is also a
LoCase
function.
Lo
, Hi
, Swap
functions: not built-in, but
available in the System
unit.
