Bbcbasic: Variable: Initialize: Can you declare the value of a 
variable when you initialize it?

---

No.

---

What does happen is when you use LOCAL then
that variable is initialized by default to
zero or the empty string.

You have thus to set that variable after you used
LOCAL.

===

e.g.

This will give a syntax error:
('not in a function')

--- cut here: begin --------------------------------------------------

PROCt
END
:
:
:
DEF PROCt
 LOCAL myinteger1 = 10
END

--- cut here: end ----------------------------------------------------

---

e.g.

This will not give a syntax error:

--- cut here: begin --------------------------------------------------

PROCt
END
:
:
:
DEF PROCt
 LOCAL myinteger1
 myinteger1 = 10
END

--- cut here: end ----------------------------------------------------

===

But what you can use alternatively is declaring the variable
after the LOCAL

E.g.


--- cut here: begin --------------------------------------------------

 PROCHelloWorld
 END
 :
 :
 :
 DEF PROCHelloWorld
 LOCAL K% : K% = 1
 LOCAL D% : D% = 2
 PRINT K%
 PRINT D%
 ENDPROC

--- cut here: end ----------------------------------------------------

If you run this, it will print

1

2
