With gawk :
Code:

   gsub(/[[:space:]]+/, " ")
   $0 = tolower($0);

   print "procedure",$1
}
' inputfile

Inputfile:
Code:
procedure test1
insert into xyz;
end;
procedure
test2
insert
into
xyz
end;
procedure test3
insert /* asas*/
into xyz
end;
procedure test4
inserting into xyz
end;
procedure test5
insert into abcdef
end;

Output:
Code:
procedure test1
procedure test2
procedure test3

Jean-Pierre.
Thanks for wonderful response. This is working fine for me, however I forget to mention one this, i.e. it could be "procedure" or "function". I need to consider both, however above code only taking care of "procedure". Pls find the latest file and expected output.

Expected output:
procedure test1
function test2
procedure test3

File Contain:
procedure test1
insert into xyz;
end;

function

test2

insert

into
xyz
end;

procedure test3
insert /* asas*/
into xyz
end;

procedure test4
inserting into xyz
end;

Request you to update the command ASAP.

ldgetpd

ldgetpd(3)						     Library Functions Manual							ldgetpd(3)

NAME

       ldgetpd - Retrieves procedure descriptor given a procedure descriptor index

SYNOPSIS

       #include <stdio.h> #include <filehdr.h> #include <sym.h> #include <ldfcn.h>

       long ldgetpd (ldptr, ipd, ppd ) LDFILE  ldptr ; long ipd ; pPDR	ipd ;

DESCRIPTION

       The  ldgetpd  routine returns a SUCCESS or FAILURE depending on whether the procedure descriptor with index ipd can be accessed.  If it can
       be accessed, the structure pointed to by ppd is filled with the contents of the corresponding procedure descriptor.  The isym,  iline,  and
       iopt fields of the procedure descriptor are updated to be used in further LD routine calls. The adr field is updated from the symbol refer-
       enced by the isym field.

       The PDR cannot be retrieved when: The procedure descriptor table cannot be found.  The ipd offset into the procedure  descriptor  table	is
       beyond the end of the table.  The file descriptor that the ipd offset falls into cannot be found.

       Typically, ldgetpd is called while traversing the table that runs from 0 to SYMHEADER(ldptr).ipdMax - 1.

       The program must be loaded with the object file access routine library libmld.a.
