I have an old Toshiba T6400SX LAPTOP running DOS 5.0 with Lotus 123 2.3 installed.

Not a machine I use everyday... but there is a Lotus 123 file I NEED to access on the machine.

To access the large file I need to switch the memory from expanded to extended (or is it the other way round). As it is so long SINCE I last accessed this file I have FORGOTTEN the key strokes in Lotus 123 to switch the memory.

Please can you help.

Thanks,

pajIf I remember correctly, DOS versions of Lotus used expanded memory. My guess is that you have a line in your CONFIG.SYS that is similar to:
DEVICE=C:\DOS\EMM386.EXE NOEMS
So, to give your computer some expanded memory take away the NOEMS parameter on the EMM386.EXE line. If you need MORE expanded RAM, then try adding a number after the line. If your computer has more than 32 MB of RAM, you can try
DEVICE=C:\DOS\EMM386.EXE 32767
or use a smaller number if you have 32 MB or less RAM in your computer.Hi,

Thanks for getting in contact.

As I recall there are a couple of keystrokes that can be used when in Lotus 123 to switch the memory.

It is these that escape me.

Do you have any IDEA what these keystrokes are?

Thanks
