Help for converting Oracle Script

Hello,

I have following Oracle script and trying to convert it for Postgres syntax:

= = = = = = = = = = = = = = =

prompt Enter value for monyy  (Month Year; Ex-mar02 indicating March 2002)

define MONYY = &monyy

spool create_new_lerg_&MONYY._accounts.lst

prompt create user acc_&MONYY.

create user acc_&MONYY.

  identified by lerg

  temporary tablespace temp

  default   tablespace prices

  quota unlimited on   prices;

grant normal to acc_&MONYY.;

= = = = = = = = = = = = = = =

If I enter mar02 as a input for the defined variable MONYY, then it creates the ACC_MAR02 user in the database.  Is there any equivalent for “define” statement in Postgres?  Your help is appreciated.

Thanks,

Nandu.
