Technicaly, yes. It will be in 64 mode, not 128 mode. However, in
the 64 mode, you will be able to use the 2 Mhz speed, the 80 column
display, the nemeric keypad, etc., so it feels like 128 mode.

How would I activate the 80-col screen and 2MHz mode?

USE C128

The 80 column screen is treated as device 7.
SELECT OUTPUT "U7:" // 80 column screen.
There are many additional commands for the 80 column screen.

TURBO(true/false) // sets fast mode on computer on/off.

I'm using a C64 .crt image and demo disk from the Web.
When I try USE C128, all I get is unknown package on the USE statement.

SELECT OUTPUT and TURBO must depend on C128 since they don't work.

I'm using the 64 COMAL 2.0 cartridge with Super Chip (a ROM containing
the C128 and other packages) on a 128 DCR with REU and Ramdrive.
Everything works.

SELECT OUTPUT is a base COMAL command. USE C128 activates the C128
package, making all C128 routines available to use, and enabling the
80 column display as device 7. TURBO is in the C128 package.
