I'm trying to pass a single bracket as a string to a function and am getting an error: (This is running on an 'MX470.)

> LIST
If TEST("(") Then
Print "Bracket"
Else
Print "Something else"
EndIf
End

Function TEST(S$) As INTEGER
If S$ = "(" Then
TEST = 1
Else
TEST = 0
EndIf
End Function
> RUN
[1] If TEST("(") Then
Error: Expected closing bracket
> ? MM.VER
4.07
>

Is this fixed in newer versions of the MM firmware? Or am I doing something rather wrong?

Note: if I change the "(" to a different character, such as "A", the program runs as expected.

Thanks.Edited by vegipete 2015-12-22

I see that ")" doesn't work either.

just tested your code using an MX170 running the latest 5.0 firmware and the observed behaviour is present.

some interesting variants:

[2] If TEST("tan(45") Then
Error: Expected closing bracket

but 'If TEST("tan(45)") Then' produces the output 'Something else'

cheers,
rob :-)

a$ = "("
If TEST(a$) Then
Print "Bracket"

ouch, that looks like a parser problem in the interpreter.

Yes, that does look like a bug and I can guess what is causing it. I will investigate and report back.

It is a bug and it will be fixed in the next release (due in mid January).
