Timex Basic 64 was totally
developed by Timex of Portugal and it is a extension of the Sinclair Basic to work with
the TC2048 and TC2068 special modes. Basic 64 have four versions, one for TC2048, one for
TC2068 and variations of both when the FDD system is connected.
Basic 64 Tape have a Demo of the capabilities of BASIC 64.
With Basic 64 you can have 64, 85 or 128 coluns of text and high resolution graphics (512x192). New system variables are created and the area of the Basic program is moved to the front of the second display file, so it cannot corrupt the screen.
New commands have been added:
n is the 4 or 5 channel. In the 4 channel the text is printed in 64 coluns.
In the 5 channel the text is printed in 85 or more coluns.
m is the start line, like LIST m, and n the channel number, like PRINT.
