How to fetch rows based on line numbers or based on the beginning of a word?
I have a file which will have rows like shown below,

Code:
ST*820*316054716  
RMR*IV*11333331009*PO*40.31
REF*IV*22234441009*xsss471-2762
DTM*003*091016
ENT*000006
RMR*IV*2222234444*PO*239.91
REF*IV*1234445451009*LJhjlkhkj471-2762  </SPAN>
DTM*003*
091016
RMR*IV*2223344441009*PO*40.31
REF*IV*111333331009*kjhjjkhkhk471-2762  </SPAN>
SE*000030*316054716

The user will be entering an account number 2222234444 and I have a script which will get the RMR record which holds that account number and which will be displayed to the user for editing, something like,
Code:
RMR*IV*2222234444*PO*239.91

Now the user wants the rows under RMR as well, display the RMR and the following segments until the next RMR is located. something like,
Code:
RMR*IV*2222234444*PO*239.91 
REF*IV*1234445451009*LJhjlkhkj471-2762 
DTM*003*091016

I thought of doing it by finding the line numbers of RMR and the next RMR and copying those records. Please advise me with an optimized solution
Right now I am finding the RMR row by

grep -n "^RMR.*$acct.*" file > output . Is there a simple way where I can get the other rows along with this row until I meet the next RMR

paps

PAPS(1) 						      General Commands Manual							   PAPS(1)

NAME

       paps - UTF-8 to PostScript converter using Pango

SYNOPSIS

       paps [options] files...

DESCRIPTION

       paps reads a UTF-8 encoded file and generates a PostScript language rendering of the file. The rendering is done by creating outline curves
       through the pango ft2 backend.

OPTIONS

       These programs follow the usual GNU command line syntax, with long options starting with  two  dashes  (`-').   A  summary  of  options	is
       included below.

       --landscape
	      Landscape output. Default is portrait.

       --columns=cl
	      Number of columns output. Default is 1.

       --font=desc
	      Set the font description. Default is Monospace 12.

       --rtl  Do rtl layout.

       --paper ps
	      Choose paper size. Known paper sizes are legal, letter, a4. Default is A4.

       --bottom-margin=bm
	      Set bottom margin in postscript points (1/72 inch). Default is 36.

       --top-margin=tm
	      Set top margin. Default is 36.

       --left-margin=lm
	      Set left margin. Default is 36.

       --right-margin=rm
	      Set right margin. Default is 36.

       --help Show summary of options.

       --header
	      Draw page header for each page.

       --markup
	      Interpret the text as pango markup.

       --encoding=ENCODING
	      Assume the documentation encoding is ENCODING.

       --lpi  Set the lines per inch. This determines the line spacing.

       --cpi  Set the characters per inch. This is an alternative method of specifying the font size.

       --stretch-chars
	      Indicates  that  characters  should be stretched in the y-direction to fill up their vertical space. This is similar to the texttops
	      behaviour.
