Memorypool Function
Can I use C language standard function "malloc" to allocate memory (variable-size) dynamically with the MR30?●   
Can system call of the variable-size memorypool function be issued from a handler (interrupt handler, cyclic handler, alarm
handler)?
●   
In the variable-size memorypool function, there are 4 types of memory block sizes available based on the value
(max_memsize) specified in the configuration file. Please let us know the equation for determining these 4 block sizes.

Task Description Method
According to the manual, it's not necessary to describe the ext_tsk system call for each task. Should I describe this system
calls for tasks if I want to reuse these source codes in other applications?

Interrupt
When using the MR30 OS-independent interrupt and enabling the multiple interrupts option, I enable it with "#pragma
INTERRUPT /E". Is there a similar option for enabling multiple interrupts when using in the OS-dependent interrupt? I want
to use the C language to write the source file. (Mar. 20, 2001)

System Call Return Parameter
What is the return value of a system call (can_wup, wai_flg, twai_flg, pol_flg, rcv_msg, trcv_msg, prcv_msg, pget_blf,
pget_blk) which has a return parameter and does not return an E_OK?

Makefile Preparation Method
My program stopped operating properly after I changed the message size in the mailbox function. Why? (Dec. 20, 2000)●   
Assume that I am developing an application program with MR30. When I change the output destination directory during the
compile or assemble process (specified options: -dir for compiler, -0 for assembler), MR30 will no longer link the real-time
OS kernel module. (Dec. 20, 2000)
●   
I would like to make my own makefile for the system I use with the MR30 (in other words, not use the makefile created by●
