Function
Startup module
• After an area (2 × 32 bytes) where a function that will be
registered is reserved with the atexit function, sets the
beginning label name to _@FNCTBL.
• Reserve a break area (32 bytes), sets the beginning
label name to _@MEMTOP, and then sets the next label
name of the area to _@MEMBTM.
• Define the segment in the reset vector table as follows,
and set the beginning address of the startup module.

_@cstart
• Set 0 to the variable _errno to which the error number is
input.
• Set the variable _@FNCENT, to which the number of
functions registered by the atexit function is input, to 0.
• Set the address of _@MEMTOP to the variable
_@BRKADR as the initial break value.
• Set 1 as the initial value for the variable _@SEED, which
is the source of pseudo random numbers for the rand
function.
• Perform copy processing of initialized data and execute
0 clear of external data without an initial value.
• Call the main function (user program)
• Call the exit function by parameter 0.
