Line 2 sets the Title property, which tells Small Basic the title of the
text window. Line 3 sets the BackgroundColor property to "Yellow" for all the
upcoming text outputs. The Clear() method (line 4) tells TextWindow to repaint
itself using its BackgroundColor property, which is what makes the window’s
background yellow. Try removing this line from the program to see what
changes in your program’s output.
Lines 6–8 set the cursor position to column 4, row 1 and set the foreground
color (the text color) to blue for the next output. The Write()
method at line 9 writes the string "BLUE TEXT", starting at the current position
of the cursor. The Write() method is just like the WriteLine() method,
except it doesn’t move the cursor to the next line after it displays the string.
After this call, the cursor is at column 13 but still in row 1.
Line 11 moves the cursor down to row 3. Line 12 sets the foreground
color to red, and line 13 calls Write() to display the string "RED TEXT".
Lines 15 and 16 move the cursor to column 1, row 5; line 17 sets the
background color to green. This is the last statement, so the program terminates
at this point (because there’s no more code to run). Because the
foreground color of the text window is still set to red, the Press any key to
continue... message is displayed in red on a green background.
