MODE # 0 MODE # 1 MODE # 2 MODE # 3 MODE # 4 MODE # 5 MODE # 6 Figure 11-4. Seven density modes Figure 11-4 displays all seven of the FX modes that affect graphics density. Table 11-1 describes them. More Graphics Programming Tips The next two sections discuss two modes that the FX offers to help you solve potential graphics problems. A reassigning code allows you to change the density for graphics programs that use one of the four alternate codes. The 9-pin Graphics Mode allows you to use all nine pins on each line and thus speed up screen dumps. Reassigning alternate graphics codes The FX provides a command to reassign one of the alternate graphics codes-K, L, Y, or Z-so that it represents any other of the seven Graphics Modes. The command and its format are: LPRINT CHR$(27)"?s"CHR(n); where s is one of the four symbols, K, L, Y, or Z, and n is one of the numbers used with the ESCape " *" command, 0 to 6. There are several instances in which you may use this sequence. The first occurs if you have written a program to be printed in one Graphics Mode and now want to print it in another. If you have used concatenation to store your Graphics command strings in one short character string, that will not be difficult. You can simply change the mode number or alternate code in the definition of the character string. In the program for Figure 11-4, for example, you did this in line 20 by storing the Graphics Mode command sequence in A$ and making 150
