Missed syntax error in Fill statement rhs

[jodavies]

In the following, FORM proceeds with no error.

Symbol x;          
Table tab(0:1);    

Fill tab(0) = 1 x; 
*Fill tab(1) = 1 x;

.end               

If one uncomments the second Fill statement, FORM reports

test.frm Line 5 --> Warning: Table element was already defined. New definition
will be used

Thanks, Josh.

As it should! tab(0) = 1 x; is interpreted as tab(0) = 1,x; as explained in the manual. And with 1,x it fill two table elements. and hence the compiler is right.

Btw. I also run sometimes into tricky things like this where you just don’t see what went wrong, until suddenly you see something seemingly insignificant and it turns out that indeed the compiler was right.

Cheers

Ah, OK! I didn't realize that that syntax for filling multiple elements was allowed.

Thanks!
