Reading specific lines in a file

Question

hI
i need to write a program which has a file name a.txt the contents in the file is
SELECT DISTINCT D.MENUNAME, D.MENULABEL, D.MENUSEP, D.MENUORDER FROM PSMENUDEFN D, PSAUTHITEM A, PSOPRCLS C WHERE D.INSTALLED = 1 AND D.MENUGROUP = :1** AND D.MENUNAME = A.MENUNAME AND A.AUTHORIZEDACTIONS > 0 AND A.CLASSID = C.OPRCLASS AND C.OPRID = :2** ORDER BY D.MENUORDER, D.MENUNAME
Bind-1 length=21 value=&Administer Workforce
Bind-2 length=6 value=NLWAJP
I need to read the file in such a way that in the SQL statement in the place of ":1" I need to get Bind-1 value i.e., &Administer Workforce and same with :2 I need to get Bind 2 value NLWAJP
Output must be like this
SELECT DISTINCT D.MENUNAME, D.MENULABEL, D.MENUSEP, D.MENUORDER FROM PSMENUDEFN D, PSAUTHITEM A, PSOPRCLS C WHERE D.INSTALLED = 1 AND D.MENUGROUP = &Adminster Workforce AND D.MENUNAME = A.MENUNAME AND A.AUTHORIZEDACTIONS > 0 AND A.CLASSID = C.OPRCLASS AND C.OPRID = NLWAJP ORDER BY D.MENUORDER, D.MENUNAME
