RIGHT CLICK ON STORED PROCEDURE IN ENTERPRISE MANAGER AND START WRITING FOLLOWING CODE
YOUR NEED TO CREATE TWO PROCEDURES
ONE FOR INSERT INTO FIRST_TABLE
ONE FOR INSERT INTO SECOND_TABLE

CREATE PROCEDURE INSERT_FIRST
(
@PK_COL INTEGER OUTPUT,
@OTHER_COL VARCHAR(25)
)
AS

    SELECT @PK_COL =ISNULL(MAX(PK_COL),0)+1 FROM FIRST_TABLE
    INSERT INTO FIRST_TABLE (PK_COL,OTHER_COL) VALUES(@PK_COL,@OTHER_COL)

----------SECOND
CREATE PROCEDURE INSERT_SECOND
(
@PK_COL INTEGER ,
@OTHER_COL1 VARCHAR(25)
@OTHER_COL2 VARCHAR(25)
)
AS

    INSERT INTO FIRST_TABLE (PK_COL,OTHER_COL) VALUES (@PK_COL,@OTHER_COL1,@OTHER_COL2)

--HOW TO CALL FROM QUERY ANALYSER
DECLARE @PK_COL_TMP INTEGER
EXEC INSERT_FIRST @PK_COL=@PK_COL_TMP,@OTHER_COL='SOME VALUE'

--NOW @PK_COL_TMP WILL HAVE NEW GENERATED VALUE
EXEC INSERT_SECOND @PK_COL=@PK_COL_TMP,@OTHER_COL1='SOME VALUE1',@OTHER_COL2='SOME VALUE 2'

--TO CALL FROM FRONT END EVERY FRONT END HAS ITS OWN SET OF SYNTAX TO CALL STORED PROCEDURE AND TO RETRIVED OUTPUT TYPE OF

PARAMETER YOU HAVE TO REFER FRONT ENDS MANUAL

there is mistake in second procedure,
following is correct code

INSERT INTO FIRST_TABLE (PK_COL,OTHER_COL1,OTHER_COL2) VALUES (@PK_COL,@OTHER_COL1,@OTHER_COL2)

in the begining of procedure after keyword AS
BEGIN TRANSACTION

-YOUR CODE
-.....

IF (@@ERROR<>0)
COMMIT TRANSACTION
ELSE
ROLLBACK TRANSACTION

Also you should write one stored procedure for each table. do not write everthing in one procedure. Error message will come to your front end code directly. Print command will not help it will show message only if you execute query in query analyser.
