[comp.sys.ibm.pc] QuickBasic 4.5 and 640x400 screen on Toshiba laptops

ddfr@tank.uchicago.edu (david director friedman) (05/08/90)

I am trying to figure out how to get QuickBasic 4.5 to work with the
Toshiba 1000SE's DCGA (640x400) screen. QB4.5 supports the DCGA on
Olivetti and AT&T 6300's, but if you use the appropriate command
(SCREEN 4) on the Toshiba, you get an error message.

The Microsoft knowledge base has an article about patching Windows to
work with the Toshiba 3100, which is also DCGA. You change 40 to 74
in a few places. I have been trying to figure out how to do the
equivalent for QuickBasic. Has anyone solved this problem? I have
spoken with people at both Microsoft and Toshiba, but so far have not
gotten much help.
