Subj : Something strange going on.

Hi,

I found something odd today in the powerful CBM BASIC v2.0.

Having worked with Sinclair BASIC quite a lot recently, I use GOTO X where X is 
a valid line number (i.e., LET X = 100). But I know that's not possible with 
Microsoft BASIC. Of course there is the ON X GO TO 100,200 ...

So I thought "I know, I'll try and use a function, could CBM BASIC use this as 
a look up table". The following, I expected to go to the value in the function 
A() which returns 10, but...

0 DEF FN A(X) = 10
1 PRINT FN A(0)
2 GO TO FN A(0)
3 PRINT "END GRACEFULLY"
4 END
10 PRINT "STOP"
11 STOP

Try it for yourself. What's going on here?

Thanks in advance.

Shaun.
