use UTL_FILE to open a file, write those script statements to the file, then close the file. For example call it /tmp/env.sh

Code:

# ........ sql code goes here in  a here document

sqlplus -s username/password@somedbname <<EOF
SET serveroutput ON
DECLARE
   recordtype   varchar2 (6)      :='DBASE1'; 
   SHELL        VARCHAR2 (36);
   SHELL1        VARCHAR2 (36);
   SHELL2        VARCHAR2 (36);
   PARMS        VARCHAR2 (36);
   SQR          VARCHAR2 (31);
   SQLq          VARCHAR2 (36);
   CTL          VARCHAR2 (36);
   TNS_ADMIN    VARCHAR2 (44);
   ORACLE_HOME1 VARCHAR2 (44);
   PATH1        VARCHAR2 (30);
   FP           UTL_FILE.FILE_TYPE;

CURSOR XXX_cursor IS
 SELECT  PROGRAM_ID,STRING_ID,LABEL_ID,STRING_TEXT,COL_WIDTH from PS_XXX_ENV_VARS
           WHERE PROGRAM_ID =  recordtype;
 XXX_VARS XXX_cursor%ROWTYPE;
BEGIN
    IF NOT XXX_cursor%isopen THEN
       OPEN XXX_cursor;
    END IF;
    
   FP:=UTL_FILE.FOPEN('/TMP','ENV.SH','W');
   LOOP
    	fetch XXX_cursor into XXX_VARS;
    	EXIT WHEN XXX_cursor%notfound; 
    	 SHELL2 := XXX_VARS.STRING_TEXT ;
    	 SHELL1 := XXX_VARS.STRING_ID;
    	UTL_FILE.put_line (FP, SHELL1||'='||SHELL2);        
   END LOOP;
   UTL_FILE.FCLOSE(FP);
   CLOSE XXX_cursor ;
END;
  exit
EOF

service(8)						      System Manager's Manual							service(8)

NAME

       service - run a System V init script

SYNOPSIS

       service SCRIPT COMMAND [OPTIONS]

       service --status-all

       service --help | -h | --version

DESCRIPTION

       service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working
       directory set to /.

       The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT.  The  supported  values  of  COMMAND  depend  on  the
       invoked	script,  service  passes  COMMAND and OPTIONS it to the init script unmodified.  All scripts should support at least the start and
       stop commands.  As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the  start
       command.

       service --status-all runs all init scripts, in alphabetical order, with the status command.

EXIT CODES

       service calls the init script and returns the status returned by it.

FILES

       /etc/init.d
	      The directory containing System V init scripts.

ENVIRONMENT

       LANG, TERM
	      The only environment variables passed to the init scripts.

SEE ALSO

       /etc/init.d/skeleton,
       update-rc.d(8),
       init(8),
       invoke-rc.d(8).
