I am confused Smilie

Hope you get it..
Okay Goutam, Answer for post #7

Code:
$ awk -F, 'f && /Type:/{if(count==2){print p}f=count=0}{ if($0 ~ search){f=1} else{if(f){p=sprintf("%03d%s%s%s%s",$1+1,FS,"PLAN"$1+1,FS,$3);count++}}}1;END{if(f && count==2)print p}' search='Type:lovers,Loc=South'  file

Yes it works fine Smilie. But still there is something missing in it, as in that input given #7 the last type is with East Location so no issues.

Kindly check with this input:

Code:
Type:lovers,Loc=South
003,PLAN3,60Days
004,PLAN4,60Days
005,PLAN5,60Days
Type:lovers,Loc=East
003,PLAN3,60Days
004,PLAN4,60Days
Type:lovers,Loc=South
003,PLAN3,60Days
004,PLAN4,60Days
005,PLAN5,60Days

There should not be any changes to above input.

It won't work as it needed to be. I'm checking with all possibilities for a reliable solution.

Okay check all possibilities, it works if you need explanation to understand code read this commented version of same code in post #8

Code:
awk -F, '
	 # Previously we found actual pattern and current line pattern is again type
	 f && /Type:/{
			# if lines between pattern is 2 ?
			if(count==2)
			  {
			     # print line defined in variable p
			     print p
			  }
			 
			# Reset variable
			     f = count = 0
                     }
                     { 
			# Search pattern mentioned in variable search
			 if($0 ~ search)
			    {
				# Set variable f
				f=1
                            } 
		        else{
				# pattern not found in current line but previous found
				# pattern is which we are looking for..
				if(f)
				{
				  # increment counter and define new line
				  p=sprintf("%03d%s%s%s%s",$1+1,FS,"PLAN"$1+1,FS,$3)
				  count++
				}
                            }
                    }1
		 END{
			if(f && count==2)
				print p
		    }
          ' search='Type:lovers,Loc=South' file

Sir, I have a doubt in this. The code checks lines present between two set of 'Type:' pattern, like if there is no 'Type:' in second set and if its not the same with all sets present in the file.

How to overcome this ?
