Hello! I made a code adapted from Arduino sketch. Sketch works, my code
nope =(((( Please tell, how to get working code without interrupts.

sketch
my code:
-- target PICmicro
include 12f683
pragma target CLOCK 4_000_000
pragma target OSC INTOSC_NOCLKOUT
pragma target WDT disabled
pragma target MCLR internal -- reset on pin A3
pragma target WDT DISABLED -- watchdog
pragma target BROWNOUT DISABLED -- brownout reset
pragma target FCMEN DISABLED -- clock monitoring
pragma target IESO DISABLED -- int/ext osc. switch
--
enable_digital_io() -- make all pins digital I/
O
--OPTION_REG_NGPPU = 0 -- pull-ups ON
OSCCON_SCS = 0 -- select primary
oscillator
OSCCON_IRCF = 0b110 -- 4 MHz
--
-- setting pins
alias enc_b is pin_A5
pin_A5_direction = input
alias enc_a is pin_A4
pin_A4_direction = input
-- configure PWM
pin_ccp1_direction = output
include pwm_hardware
pwm_max_resolution(1)
pwm1_on()
-- timer setup
const TIMER0_ISR_RATE = 1000 -- 1 kHz isr rate
const DELAY_SLOTS = 1 -- support slots
include timer0_isr_interval
timer0_isr_init() -- init timer0 isr
--setting variables
var byte pwm
var bit old_a
--
pwm = 0
pwm1_set_dutycycle_percent(pwm)
forever loop
if check_delay(0) then
set_delay(0, 5)
if old_a & !enc_a then
if enc_b then
if pwm!=254 then pwm = pwm + 1 end if
else
if pwm!=0 then pwm = pwm - 1 end if
end if
pwm1_set_dutycycle_percent(pwm)
end if
old_a = enc_a
end if
end loop
