Displays the amount and status of system RAM under MSX-DOS 2 / Nextor.

The following infos will be displayed:

  • amount of total RAM, free RAM, used RAM by the system, used RAM by the user, for all the available memory mappers
  • amount of free TPA. This is not the current free TPA, but the TPA available to any MSX-DOS 2 transient program (or tool)
  • amount of total history RAM, free history RAM. When this is 0 bytes, it means the history buffer is full, and that subsequently entered commands cause the first commands to be deleted from the buffer.
  • amount of total alias RAM, free alias RAM,
  • amount of total variables memory (swap RAM), free swap RAM. When the swap RAM has become too small no new shell can be started.



All parameters are optional.

Note: Character slash (/) serves to declare an option. You can put the options after the command or behind all other parameters.


/K is used to represent all figures of 1,024 bytes and over in a kilobyte unit.

/'P' to cause the output to pause at the bottom of the screen until a key is pressed.
