jumping out of a gosub reminder

[richard]

Not necessarlly, Lot of hi level programing language have this already implemented. eg in .net: On Error GoTo, Try, catch, etc...

hmm, in python at least a sub with a "try" still returns , even if the processing aborts and executes an "try" error routine.
i see no goto or stack popping going on.

a couple of python subs with try

def process_d(tname,q):    while exitflg==0:
        dx=ser.readline()
        try :
            rt='s'
            
            ff= string.rstrip(dx)   
            int(ff,16)   ##non hex chr will cause ValueError
            if dx[0]=='A':
                 rt='w'
            
            #print dx
            ts=str(datetime.datetime.now())[:19]
            r_x=[ts,dx,rt]
            queueLock.acquire()
            q.put(r_x)
            queueLock.release()
        except ValueError:
                #print dx
                dx=[]


def bag_reading ():
    global readings
    bag_data_time =datetime.datetime.now()
    if len(readings)>0:
         
       try:
           conn=sqlite3.connect('/media/CORSAIR/wh2.db') 
           curs=conn.cursor()
           curs.executemany("INSERT INTO log values((?),(?),(?),(?))", (readings))
           # commit the changes
           conn.commit()
           conn.close()
           print 'write ',len(readings),'  ',readings[-1][0]
           readings=[]
           bag_data_time += datetime.timedelta(minutes=5)
       except sqlite3.OperationalError as err :
           print 'db busy',err
           bag_data_time += datetime.timedelta(minutes=1)  
    return   bag_data_time
