This is my first tutorial
It is about subs!!!
whenever I read about subs I was always confused so I will try to make this simple for you!!!

Subs:
sub is short for sub routines
subs are used instead of the goto command.they are much easier to debug than when you use goto.
make a sub you have to type DECLARE SUB<subname>()
for example:
DECLARE SUB Whatever ()
To call a sub you just write the name of the sub where you want it to be called
for example:
DECLARE SUB Whatever ()
Whatever
this will run the sub Whatever
You are not able to use variables within subs unless you use the DIM SHARED command
for example:
DECLARE SUB Whatever ()
Whatever
DIM SHARED a$
this will allow you to use this variable in the rest of the programing
if you want to call a sub under certain conditions then you Would use the IF command!!!
for example:
IF b$="yes" THEN Whatever
this will open the sub Whatever if b$ = yes (go figure!!!)
Inside the sub you must have two commands SUB and END SUB(guess what that does!!!)
for example:
SUB Whatever
END SUB
here is an example of a program that uses a sub to print someones name
DECLARE SUB Yourname ()
INPUT "Would ya like to play!?!";play$
IF play$ = "yes" THEN Yourname ELSE END
DIM SHARED name$
PRINT "Welcome ";name$;""
end
'inside of the sub now
SUB Yourname
INPUT "What is your name";name$
END SUB
'OUTSIDE OF the sub now
SUBs are very useful if you want to have an organized program
Clear as mud???
