I need help with this pseudo-code, I need to use PERL because another piece of a process uses it too. 

## Pseudo code for counting iterations of 1 and 0 as listed on new lin
+es in a .txt

##PREPARATION WORK**
name input_file
    input_file = “C:\Video_Forensics\case_number_CV000001\frame3000-12
+034.txt”
##  this is where the script should be modified to tailor to a specifi
+c case or workstation

Create file “iterations1.txt”
##    this is the file that will be the new list counting the consecut
+ive iterations of 1
create file “iterations0.txt”
##    this is the file that will be the new list counting the consecut
+ive iterations of 0

create object_1count
    object_1count=0
##  this will count the number of times that 1 has been read since the
+ last number was 0
create object_0count
    object_0count=0
##  this will count the number of times that 0 has been read since the
+ last number was 1
##PREPARATION WORK**

##BODY**
open read-only file input_file
    ##  Open as read-only to avoid disturbing the integrity of the dat
+a set
    ##  This file should have only a 1 or a 0 written once on each lin
+e and be a .txt file
    ##  It should not be difficult to convert .csv or .xls to .txt

read line number 1 of input_file

If value=1,
    run loop1test.
else if value=0,
    run loop0test.


(loop1test)
##  this loop initiates the logic chain when the data set starts with 
+a 1 and will be 0 when it changes
    set object_1count=( object_1count + 1)
##  now the program is counting iterations of 1
    run 1start_count_loop    
(end loop1test)


(1start_count_loop)
read next line
    If line value=1,
        set object_1count=( object_1count + 1)
            run 1start_count_loop
##  The next line was still a 1, so continue counting
    else if line value=0
        write object_1count to new line of file “iterations1.txt” then
+ save and close
            set object_1count=0
                run loop0test
        else if line value = NULL (blank or there are no new lines)
            write object_1count to new line of file “iterations1.txt” 
+then save and close
(end 1start_count_loop)



(loop0test)
    set object_0count=( object_0count + 1)
    run 0start_count_loop    
(end loop0test)


(0start_count_loop)
read next line
    If line value=0,
        set object_0count=( object_0count + 1)
            run 0start_count_loop
    else if line value = 1
        write object_0count to new line of file “iterations0.txt” then
+ save and close
            set object_0count=0
                run loop1test
        else if line value = NULL (blank or there are no new lines)
            write object_0count to new line of file “iterations0.txt” 
+then save and close
(end 0start_count_loop)

close input_file
