What's the deal with the - symbol?
I'm finding that I can't use "-" anywhere, so instead of writing A := -B, I have to write A := 0--B.

There is no negation operator. Yes, it totally sucks.
I plan to provide < and > as alternatives to << and >>, but unfortunately I can't replace -- with -.
It may be safe to add - as the negation operator, removing the ability to start a token with -, which I assume noone does. I'll have to think about it a bit more.

| Out of all the many things I regret about hamsterspeak, I think the -- operator is the one I regret most :) |

Wow, take that, -1.
The worst part is that hspeak accepts "-1", but doesn't interpret it correctly.
I had an equation that started with "stuff := -1* ..." and although it successfully compiled, it would get zeroed out on me.

What? Negative numbers are supported (where the - is part of the literal rather than an operator). Maybe you found a bug; if you can reproduce it I'd like to know.

Euh ... maybe I can ... it was buried in layers of code ... but if I can do it again in a simple way, I'll let you know.

Wait what!?
I know for a fact that I've used negative numbers before! I think it was in Star Wohr. Though, i suppose it could have been the cause of some of the bugs in that game...
..oh noes. |

Well, once I substituted
with
my script worked :-S
I've used "-1" before too, (and it worked), but in this instance it didn't.
I haven't always been coding in OS X though ... Linux and Windows denote end-of-line in different ways ... might this also be the case for "-"?

line endings are the only difference between linux/windows text files. There are no differences with any other characters.
I cannot reproduce this with a simple test case
| Code: |
include, plotscr.hsd
script, foo, begin
variable(bar)
show value(-1*bar)
end
|
I couldn't even guess what may have caused your problem.
However, it is indeed a known malfeature that you can't do this:
| Code: |
include, plotscr.hsd
script, foo, begin
variable(bar)
show value(-bar)
end
|
because you will get this error:
| Code: |
Semicompiling m.hss to m.hs
reading m.hss
including plotscr.hsd
1566 lines read from 2 files
preliminary pass
parsing top-level
compiling scripts....................................................................................................................................
ERROR: in script foo on line 5 in m.hss
show value(-bar)
^
Unrecognised name -bar. It has not been defined as script, constant,
variable, or anything else
