Beginner level question

Hi, I am newbe to this forum and to PIC programming.
Earlier tried 2 small projects by using MPASAM, but found it bit tricky to handle. So, I am learning to use GC Basic. 
I want to use 16F628 (which is available for me to play with) and screen the pulse input, and allow only certain pulses that are more than 400 mSec, as pulse output.

I wrote the following code and sucessfully compiled it. Yet to test in PIC.
*******************************
# chip 16F628, 4MHz
LET Count = 0;
LET Output = 0;
Start:
      IF Input = 0 THEN
         IF Count = 0 THEN
         Wait 100 ms
         GOTO Start
         END IF
         IF Count <> 0 THEN
              Count = 0
              Output = 0
              Wait 100 ms
              GOTO Start
         END IF
      END IF       
      IF Input <> 0 THEN
         Count = Count + 1
         IF Count = 4 THEN
            Count = 0
            Output = 1
Output_on:
            IF Input = 0 THEN
               Output = 0
               Goto Start
            END IF
            IF Input <> 0 THEN
               Wait 100 ms
               Goto Output_on
            END IF
         END IF     
         IF Count <> 4 THEN
               Wait 100 ms
               Goto Start 
         END IF
      END IF

My questions are:
The 'compiled.asm' file shows that the chip is 16F819 instead of 16F628 as I wanted?.
I have not defined (not sure how to) the input and output ports in my code above, so which pins are being used?
Thanks in advance,
Ravi

try this:
in beginning of code if potb.0 is input and porta.0 is output:
#define input portb.0
#define output porta.0

then in startup section add command to set pota.0 ar output:
dir output out

this can be ound on help section.
try to read all help for our reference an learning.
also look on example codes...

Just try :
#chip 16F628, 4MHz

instead of
# chip 16F628, 4MHz

Thanks for the suggestion. Ravi
