I have function for caseless compare:
int strnicmp (const char *s1, const char *s2, int maxlen) {
char c1, c2;
do {
c1=*s1++;
if (c1>='a' && c1<='z') c1&=0xDF;
c2=*s2++;
if (c2>='a' && c2<='z') c2&=0xDF;
// problematic code
if (c1==c2) maxlen--;
} while (maxlen && c1
Thanks for Your message. I tried to look for such bug fix in changelog
but not succeeded. I will try newer version now.

Hi,
I would use something like:
for (i=0; i<4; i++)
char_counter[i] = ((unsigned char*)&long_counter)[i];
for (i=0; i<4; i++)
((unsigned char*)&long_counter)[i] = char_counter[i];

Hello,
I want to start project with Z180 but I can't find some answers:
- I get "ASlink-Warning-No definition of area HOME" but I don't know why
- the code in .IHX file is placed at address 0x0020 (not 0x)
- there is not default crt0 linked (i.e. SP setup etc.)
- how to write bigger applicat
Thanks for Your reply.
after some more time of testing I got finally correct result. There was
missing option for linker, so Z80 objects were linked as if they were
for i51. It is probably also the cause for not linking crt0 and offset
0x0020 in IHX output (it was really 0x0020, not 0x0200; se

it can't be compiled unless .globl is added for l__INITIALIZE* and

Thanks for Your reply.
I am not sure if I understand it correctly. When I need to compile
source, code should be in INITIALIZED section to get correct addresses;
INITIALIZER section will contain .ds with correct size just to make
place for initialization data after special utility is executed -
Hello,
I need to run assembly code in RAM. Is there any way how to write such
source code? I need the compiler to produce "initialization" data in ROM
which will contain the code with all addresses calculated for RAM
placement, so the code can be a part of initialized data...
Thanks,
Hynek

Thank You all for hints how to do this.
The purpose is bank switching code for Z180; RAM is common area which
has to be always mapped (stack, common variables), so this code has to
be placed there.

Hi Richard,
PICprog connection for PIC16F526 needs 5 pins: Vdd, Vss, MCLR, ICSPCLK,
ICSPDAT. You can also do programming out of Your device (ZIF socket - if
You have one - connected to PICkit), so You don't necessarily need ISCP
pins in Your design. But is is quite convenient to instantly down

Hello everybody,
is there any possibility to control assembler through define entered

With sdcc, I can used -D, but I don't see such possibility
for sdasz80.
It is quite inconvenient to edit source for various compile options...

Would it be possible to add common IRS function for all unused vectors?
This will reserve all vectors to be possibly modified later.

The last note:
if bitfield in SDCC for the first time crosses byte boundary, it always
starts at bit zero. The strange thing is that second example produces 3
byte long structure (no 4 bytes long) so second byte-boundary crossing
seems working correctly.
