PWM in LMD18200 and 16F628a

[evilopinions]

Just trying to get this code to work.....

#define INC  PORTA.F5
#define DEC  PORTA.F6
#define STOP PORTB.F2
#define DIR  PORTA.F7


char *txt1 = "ACTUAL: " ;
char *txt2 = "REQ: "    ;
int act    = 0          ;          // Stores the actual number of pulses
int revsreq = 0        ;
char atxt[4]            ;          //
char rtxt[4]            ;
char duty_v = 100         ;

void main()
{
CMCON = 0x07; //digital mode
TRISA  = 0b00000100;
TRISB  = 0b00000100;
 PORTA.F3 =   0 ;
 PORTB.F3 =    1 ;
  PORTA.F2 =   1 ;
 }
/*LCD
//LCD_Custom_Config(&PORTB,7,6,5,4,1,&PORTA,1,0);

          act = TMR0   ;       // act stores the count on timer0 in one second

          duty_v =(revsreq - act)*1 + duty_v     ;
          if(duty_v>255){duty_v = 255;}
          if(duty_v< 0 ){duty_v =   0;}
          PWM_Change_Duty(duty_v);

          if(INC==1)
          {revsreq = revsreq+4;
           if(revsreq>40) {revsreq = 40;}
           }

          if(DEC=1)
          {revsreq =revsreq-4;
          if(revsreq<0){revsreq=0;}}

          if(DIR==1)
          {if(PORTA.F2 == 0)
            {PORTA.F2  =1;}
           if(PORTA.F2 ==1)
           {PORTA.F2=0;}
           }

          if(STOP==1)
          {PORTA.F3=1;}

          bytetostr(act/4,atxt);    // Changes actual pulses into revolutions and convert it into string
          Lcd_Custom_Out(1,1,txt1)    ;    // Displays "ACTUAL" on the LCD
          LCD_Custom_Out_CP(atxt)     ;    // append data


          bytetostr(revsreq/4,rtxt);// Changes required pulses into revolutions and convert it into string
          Lcd_Custom_Out(2,1,txt2)    ;    // Displays "REQ:" on the LCD
          Lcd_Custom_Out_cp(rtxt)     ;    // append data
          }
           }

Can someone actually look at it and tell me where am I going wrong...

Even the LCD is not functuning correctly...It lights up but displays nothing....

PIN 1,2,9 in 16F628a correspong to direction , Brake and PWM....(RA2 , RA3, RB3)
