Can you create a ONE LINE ACL that permits the range 10.0.0.0 - 10.192.255.255 or would you have to do it in separate statements?

I am not sure, but I think you have to do it with multiple statements:
10.0.0.1 255.128.0.0 (0 - 127)
10.128.0.1 255.192.0.0 (128 - 191)
10.192.0.1 255.255.255.0 (192)

Hello,
no, it is not possible. If you write it down as binary :
10.0.0.0 00001010.00000000.00000000.00000000
10.192.255.254 00001010.11000000.11111111.11111110
you can reveal, that the only common part what can be masked is the first octet, that is, with one mask you can specify only the whole class A 10.0.0.0 address range.
