My port access statement is not properly generated as a binary code when I use the optimization option. Why not?●   
Since sequential bit accesses are grouped into one operation, an interrupt occurring during this operation sometimes causes
my program to mis-operate. What can I do to avoid this?
●   
When compiling with the NC30 V.3.00 (non-optimized), the code size is sometimes larger than in the NC30 V.2.00. Why?●

Install
I bought the NC30WA package. I was able to install NC30 properly with the included license ID, but I could not install AS30
with the same ID. Do I need to obtain a separate license ID for AS30, too? (Jul. 21, 2000)

Comments
When I put "/*" in a comment starting with "//", the compiler generates an error. Can't I use this character combination? (Jul.

[Example program]
 main()
 {
         //  /* abc
 }

Registers
Which registers are stored in the stack when calling a function? (Dec. 20, 2000)●   
I want to assign all registers (R0, R1, R2, R3, A0, and A1) as register variables. Is it possible to do this with the NC30
compiler? (Jul. 21, 2000)
●   
Can the NC30 compiler assign a register for local variables when the optimization option is specified? (Jul. 21, 2000)●   
I want to use register variables with the NC30 compiler. How can I do that? (Jul. 21, 2000)●
