PLEASE HELP!!! multiple error messages in SS2K5

I have a SS2K5 stored procedure that executes 2 others stored procedures
sp_zero1 and sp_zero2
sp_zero1 and sp_zero2 do the same thing ... raises an Divide by zero error
I need to (print / select into a database) both error messages using just one
try catch block instead of 2 blocks like in the next example:

-- THIS IS THE WORKING CODE THAT I DONT WANT
BEGIN TRY
exec sp_zero1
END TRY
BEGIN CATCH
PRINT ERROR_MESSAGE()
PRINT ERROR_PROCEDURE()
END CATCH
BEGIN TRY
exec sp_zero2
END TRY
BEGIN CATCH
print ERROR_MESSAGE()
print ERROR_PROCEDURE()
END CATCH

if I try the next code

--THIS IS THE NON WORKING CODE
BEGIN TRY
exec sp_zero1
exec sp_zero2
END TRY
BEGIN CATCH
print ERROR_MESSAGE()
print ERROR_PROCEDURE()
END CATCH

only the first error message is printed and the execution is stopped

This is a generic example ... in reality I have a stored procedure that executes tens and hundreds of other stored procedures ... so thats the reason I need just one block of try catch instead of hundreds of blocks

thank you
