PROBLEM CALLING FUNCTIONS WHICH ALL WORKED WHEN THEY WERE PROCEDURES

I USE THE FOLLOWING TEXT FILE (TEST_FUNCT) TO CALL A FUNCTION USING THE PERSONAL ORACLE7 FOR WIN95. DECLARE
RECV_NUM NUMBER;
RECV_NUM := FUNCTION_NAM(FUNCTION PARAMETERS); /

• WHEN I TRY TO EXECUTE THE ABOVE BY USING "START C:\TEST_FUNCT;" COMMAND, ORACLE SENDS BACK A COMMAND THAT IT WAS LOOKING FOR SOMETHING ELSE WHEN IT ENCOUNTERED THE "=" SIGN. WHEN I "START C:\FUNCTION_NAM" I GET A MESSAGE THAT THE FUNCTION WAS PROPERLY CREATED. I ORIGINALLY HAD THE FUNCTIONS AS PROCEDURES AND THEY ALL WORKED. NO I WANT TO RETURN ERROR CODES AND NEED THEM TO BE FUNCTIONS. I KNOW HOW TO DO THE SAME THING WITH PROCEDURES I JUST WANTED TO TRY IT AS A FUNCTION. THERE MUST BE SOMETHING I AM OVERLOOKING SUCH AS HOW TO CALL THE FUNCTION. TO CALL PROCEDURES I USED THE "EXECUTE" COMMAND. IS THERE SOMETHING LIKE THIS FOR FUNCTIONS?
