The following list describes the functions which are available in this mode, note that the use of prelink is not allowed to resolve library objects automatically. The nolib option can be used to build user specified objects into a single E/XSD object.
!WARNING! @@DIVI64 and @@DIVU64 cannot be used in systemr programs. These are automatically generated when long long variables are divided in user-code.

Unlike systems mode, setjmp and longjmp are not properly supported by systemr since the local
memory allocated will not be deallocated at the end of the function.socket.c may be recompiled and used with EZASOKET in systemr mode. errno and the errno.h header file must be replaced with a non-thread aware version, and the inet_addr and inet_aton functions must be removed to prevent the use of strstr and atol which aren't supported in systemr mode.
The full-screen terminal functions may also be used - these include memory allocation routines for 24 bit addressable memory.
