In bash this works:
var1=abc
But this gives an error:
var*1=abc
var*1=abc: command not found
Why so? Why is the expression treated as a command?

From http://www.gnu.org/software/bash/manual/bashref.html
The value on the left hand side is not an identifier. It is an expression. Therefore that command (to evaluate the entire expression) is invalid.
In other words, you can’t have asterisks in names, and you can’t generate a variable name by doing some math (multiplying).
