How can one remove extra EG code from exported code files

[PhilC]

I think I've read someone suggest SED script without posting a script. Are there any other ideas?  I am familiar with SED, but I'm failing to make it work. 

I want to process a set of files and remove the line with "GOPTIONS ACCESSIBLE;" and all lines before, as well as the line with "GOPTIONS NOACCESSIBLE;" and all lines after. 

/* ----------------------------------------
Code exported from SAS Enterprise Guide

/*... blah blah...*/

GOPTIONS ACCESSIBLE;

/* ***************************** */
/* My Code, which I want to keep */
/* ***************************** */
%Macro Table_Lookup(command,result);
  /* etc. etc. */
%mend;

GOPTIONS NOACCESSIBLE;
%LET _CLIENTTASKLABEL=;
/*... blah blah...*/

Ok I figured it out.

Removes the header defined by the last line which is a match for "STRING IN THE LAST LINE OF THE HEADER" and the footer defined by the first string which is a match to "STRING IN THE BEGINNING OF THE FOOTER".

Its up to the user to find appropriate and unique match strings to make this work.

/STRING IN THE LAST LINE OF THE HEADER/h
/STRING IN THE BEGINNING OF THE FOOTER/bbeginprint 
x
/STRING IN THE BEGINNING OF THE FOOTER/bprint
d
:print
x
p
d
:beginprint
h
d

Using sed command line:

sed -i -n -f "script file_name.sed" "file name.sas"

The SED version I am using is GNU SED version 4.2.1, on Windows 10.
