RE: *Zeros

That is kinda freaky though....i got the same compile error, etc. seems
that free format is a little finicky about *ZERO in this form.  Using
fixed format for the same code compiles fine:
c                   eval      w#ladj = 0-dlsqty*dlstks   

Maybe you found a bug... 


Thanks,
Tommy Holden

Not really the answer but...

Why w#ladj = *Zeros - dlsqty * dlstks;
Seems you want to make the resulting number a negative?

FWIW I would just do this:
W#ladj = (dlsqty * dlstks) * -1;

Subject: *Zeros

Got a "strange" compile error message a few minutes ago:

RNF7421 30 1 Operands are not compatible with the type of operator.

The line in error read: w#ladj = *Zeros - dlsqty * dlstks;

When I changed *Zeros to simply 0, the program compiled without a
murmur.

So I pulled out the trusty (dusty) ILE RPG Reference manual. Page 126
says:

"*ZERO/*ZEROS Character/numeric fields: All zeros. The value is '0' or 
X'F0'. For numeric float fields: The value is '0 E0'."

So I'm thinking (always dangerous), "Oh, *Zeros is a character field."

But, then, I remembered another line in this same program (and similar 
lines in tons of other programs:

w#ladj = *Zeros;

I scanned some old, fixed-format code and found things like: *Zeros ADD 
X Y.
Which means (to me, anyway) that *Zeros is a numeric field.

So, why did I get the compile error?

Thanks.
