I'm confused about the mnemonics of the assembly. A typical statement looks like
NOOP [-v,-h,-d] #640 Am I correct in concluding that -v and -h refer to the vblank and hblank assertions? In the program Timothy posted, every instruction has the -d modifier. Does this mean that some programs will never need to assert the data line, or is this an oversight? Also, how is cursor control reflected in the mnemonics? Finally, is it really a good idea for the mnemonics to reflect hardware details? I'm referring to the part in brackets here. All a programmer cares about is whether the signals are asserted; he shouldn't have to care whether they are active low or active high. I'm proposing something like NOOP [v,h] #640 where only the asserted signals are listed between the brackets instead of stating whether the lines are high or low. Timothy's program already does this for returns. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
