The final step to plotting a circle in an array is to close the loops and display the contents of the array. Add these three lines to your program:

50 LPRENT A(R,C);: NEXT C: LPRINT60 PRINT "ROW";R: NEXT R170 LPRINT CHR$(27)"@": END

and RUN it.

Figure 13-6. Displaying an array

The printout shows, in terms of ones and zeros, the results of your planning and your program’s plotting.

Ones become dots

Next you need to translate the contents of the array to dots on the paper. First, modify line 50 so that it no longer prints out the contents of the array:

50 NEXT C

Then fill the usual graphics prescription for 7-dot line spacing:

70 LPRINT CHR$(27)"1"CHR$(7);

The CHR$(7) sounds the beeper to tell you when the array is full.
