; ColorPRINT is a MODE 2 characater printing tool for the Timex TC2048 and

; Spectrum SE computers. It uses channels/streams to extend 48 or 128 BASIC.

; Use it with PRINT #4 CHR$ n (where n is 0 to 255). The co-ordinates are taken

; from the standard screen channel. To print at a specific co-ordiante use

; PRINT AT y,x; #4; "some text";. All 256 characters can be redefined. USR "A"

; is the first byte of the bitmap of character 144. USR "A" + 2048 is the first

; byte of the attributes of character 144. In the font area, USR "A" - 376 is

; the start of the bitmap of 'a', while USR "A" - 632 is 'A' and so on (the

; CHARS and UDG system variables are changed to point at the new data area).

; PRINT, PLOT, CIRCLE and DRAW now function on the bitmap only and will not

; modify the attributes.
