Takeshi --
If you're an emacs user like I am, I'm noting that it's not doing a good
job of highlighting 'label' in a way that might clue a user into realizing
that it was reserved... :'(
vim seems to be doing a better job with 'label' (but is clearly a far
inferior editor, so that's not a real solution... :)

Dear Nikhil,
I see, this is a keyword for "label"ing for-loops etc... XD
I will try to search the Language Spec PDF from the next time :-)
Thanks very much,

Dear Takeshi,
"label" is a Chapel keyword (for loops)....
See the Chapel language spec here :
http://chapel.cray.com/docs/latest/_downloads/chapelLanguageSpec.pdf
Sec 6.4.2 and Sec 11.10 in particular.....
Cheers,
-- Nikhil

Hello,
In the following code, I am trying to print a simple string
and the value of x:
---- test.chpl ---
// proc foo( label, x ) {
// writeln( label, " : ", x );
// }
proc Foo( Label, x ) {
writeln( Label, " : ", x );
}
proc bar( msg, x ) {
writeln( msg, " : ", x );
}
var x = 1.23;
// foo( "foo", x );
Foo( "Foo", x );
bar( "bar", x );
--------------------------
The only difference among foo(), Foo(), and bar() is
the name of the first formal argument (i.e., "label" vs "Label"
vs "msg").
The functions Foo() and bar() work as expected,
while if I uncomment the definition of foo(),
the following error occurs:
test.chpl:2: syntax error: near 'label'
where line 2 refers to
proc foo( label, x ) {
So it seems that the variable name "label" has some problem,
but I cannot find a keyword such as "label" from the online
manual.
Is there something strange with my code above, or am I
missing something...?
With best regards,
Takeshi Yamamoto
