What happened?

HACK ASM program:

@12000
D=A
@$foo
M=D

Expected result: Successfully assembled to following .HACK file:

0010111011100000
1110110000010000
0000000000010000
1110001100001000

Actual result: Got error: Line 3: expected ".", a digit, "_", or a letter

According book 6.2.1, dollar sign ($) should be accepted as valid symbol.

A user-defined symbol can be any sequence of letters, digits, underscore (_), dot (.), dollar sign ($), and colon (:) that does not begin with a digit

Java version assembler 2.5 successfully assembled as expected.
