variable declaration

[k-eks]

There are some minor inconsistencies with variable declaration: Cell 5 5 5 90 90 90 b=1; #works fine b = 1; #parse error pointing on the previous line (manual mentions that no spaces are allowed) b=1 #(no semicolon) parse error pointing on the previous line

in contrast to RefineableVariables [ b=1; #works fine b = 1; #works fine b = 1 #works fine b=1 #works fine ]

Also error bars are allowed here

RefineableVariables [
b=1.01(3); #works fine
]

but not here:

Cell 5 5 5 90 90 90
b=1.01(3); #fails

Basically all of the hassle about the whitespace comes from the following:

Cu  1   0 1 -0.5 0   0 #six numbers
Cu  1   0 1-0.5  0   0 #five numbers

And I do not know how to reliably distinguish unary - and + from operators - and +.

Aha! Thank you for the insight! Also, it's interesting with the error bars, although I hvae no idea why to use them at the moment...

Yell outputs them after refinement is finished. So they are allowed in the input to make a simple copy-paste possible.
