>sdcc area02.c
?ASxxxx-Error-<q> in line 113 of area02.asm
<q> missing or improper operators, terminators, or delimiters removing area02.rel

The offending code is:
;--------------------------------------------------------
; code
;--------------------------------------------------------
.area (CODE)
Note the missing area name.

In SDCC.lex, the switch cases:
case P_CODESEG: and case P_CONSTSEG: do not handle the buffer properly (the get_pragma_token call to check for end of line blows away the token containing the token dbuf containing the name).

Similarly, the command line processing for the corresponding --codeseg and --constseg options do not append (CODE) qualifier to the area string.

The (CODE) extension should not be appended on z80 target!

Lin Rongrong reported the problem:

1. in src\SDCCmain.c, line 1154-1163, the "--codeseg" option is handled wrong, will cause as-z80.exe report "Error: <u> undefined symbol encountered during assembly". Modify line 1159:
dbuf_printf (&segname, "%-8s(CODE)", getStringArg (OPTION_CODE_SEG, argv, &i, argc));
to
dbuf_printf (&segname, "%-8s", getStringArg (OPTION_CODE_SEG, argv, &i, argc));
solved this problem.
