Read Concurrent Parameters in UNIX shell script

Often when concurrent program is created on a shell script there is a need to extract parameters passed from concurrent program in the shell script.
In Shell Script, $1 is the variable that stores following information
- Concurrent Program Short Name
- Request ID
- Login Information(APPS username and password)
- User Id
- User Name
- Printer Name
- Save output Flag
- Print number of Copies
- List of concurrent program parameters

Following code can be used to extract different values

requestid=`(echo $1 | cut -f2 -d' ' | cut -f2 -d= | tr -d '"' )`   #request_id
login_usr_pwd=`(echo $1 | cut -f3 -d' ' | cut -f2 -d= | tr -d '"' )` #database username/password
conc_user_id=`(echo $1 | cut -f4 -d' ' | cut -f2 -d= | tr -d '"' | cut -c1-8)` #userid
conc_user_name=`(echo $1 | cut -f5 -d' ' | cut -f2 -d= | tr -d '"' | cut -c1-8)` #username
prog_param1=`(echo $1 | cut -f9 -d' ' | tr -d '"' )`  #parameter 1 
prog_param2=`(echo $1 | cut -f10 -d' ' | tr -d '"' )`  #parameter 2 
prog_param3=`(echo $1 | cut -f11 -d' ' | tr -d '"' )`  #parameter 3 
prog_param4=`(echo $1 | cut -f12 -d' ' | tr -d '"' )`  #parameter 4 
prog_param5=`(echo $1 | cut -f13 -d' ' | tr -d '"' )`           #parameter 5 
prog_param6=`(echo $1 | cut -f14 -d' ' | tr -d '"' )`           #parameter 6

When connecting to SQLPLUS in shell script, it is always advisable to extract database username and password from parameter($login in our example above) and not hard-code the value in program.
