How is a SELECT statement used in VHDL?
Assigning signals using Selected signal assignment Select statements are used to assign signals in VHDL. They can only be used in combinational code outside of a process. A selected signal assignment is a clear way of assigning a signal based on a specific list of combinations for one input signal.
When to use a comma in a VHDL signal assignment?
If you use a signal with a long name, this will make your code bulkier. Also, the separator that’s used in the selected signal assignment was a comma. In the conditional signal assignment, you need the else keyword. More code for the same functionality. Official name for this VHDL when/else assignment is the conditional signal assignment
Where can I find the VHDL Language Reference Manual?

How are variables and signals assigned in VHDL?
Variables vs. Signals in VHDL. Variables are assigned using the := assignment symbol. Signals are assigned using the <= assignment symbol. Variables that are assigned immediately take the value of the assignment. Signals depend on if it's combinational or sequential code to know when the signal takes the value of the assignment.
