Cannot find what does it mean $ and #

[Altera_Forum]

Hello! Please explain me what does mean operators $ and# in a such string: 

aneb_result_wire[] = ((data_wire[0..0] $ data_wire[1..1])# (data_wire[2..2] $ data_wire[3..3]));  I have been seeking in all sources and nowhere found answer. Thank you.

The $ is an exclusive or operator where the # is the 'normal' or operator, at least that is what they are in AHDL. 

For completeness: & is the and operator and ! is the not operator.

The code you posted is AHDL. Who told you it was VHDL?
