into the BBC BASIC for Windows LIB directory, this should be "C:\Program 
Files\BBC BASIC for Windows\LIB" if you have installed BBC BASIC for Windows 
in the default installation directory.  If you wish to remove this library 
you should delete these two files.

To make use of the functions in this library in your own programs you should
add the following lines to the initialisation routine.

      INSTALL @lib$+"MAlloc.bbc"

Interface
=========

DEF FNm_alloc(size%)
--------------------
Allocates a block of memory, returning a pointer to the start of memory, or
zero if the allocation failed.

Usage example:

      mem% = FNm_alloc(size%)

DEF FNm_zalloc(size%)
---------------------
Allocates a block of memory, returning a pointer to the start of memory, or
zero if the allocation failed.  The contents of the allocated memory is
initialised to all zeros.

Usage example:

      mem% = FNm_zalloc(size%)

DEF PROCm_free(RETURN mem%)
---------------------------
De-allocates a block of memory allocated with FNm_alloc or FNm_zalloc, the
pointer (mem%) is set to zero.

Usage example:

      PROCm_free(mem%)

DEF FNm_realloc(mem%, size%)
----------------------------
Resizes a block of memory previously allcoated by FNm_alloc, FNm_zalloc or
FNm_realloc.  The new size is specified by size%.

Usage example:

      mem% = FNm_realloc(mem%, size%)
