Hello Jan
so I have changed it:
void isr(void) interrupt 0x1
0x2 doesn't work too.
And here are parts of .asm, .map, .cof.
////////////////////////////////////////////////////////////////////////
.asm -looks fine as You wrote
////////////////////////////////////////////////////////////////////////

S_ddd_ivec_0x1_isr code 0X000008
ivec_0x1_isr:
GOTO _isr
; I code from now on!
; ; Starting pCode block
S_ddd__main code
_main:
.line 35; ddd.c ADCON1 = 0xFF; //all pins as a digital ports
MOVLW 0xff
MOVWF _ADCON1
.line 36; ddd.c OSCCON = 0x6F;
MOVLW 0x6f
////////////////////////////////////////////////////////////////////////////
.map - looks fine too
