Hello there,
I am pretty beginner at assembly language and 68000. My program is suppose to intake up to 10 words or as many up to just a carriage return. The # of words, length of words and the word are stored in a list. In the format [# of words], [length of word], [word] etc etc. That is also how it is suppose to print. My program prints the correct # of words and length of words. Then prints the first letter of each word and the ending letters of the last word. So the last word is the only correct one. I've tried a lot of things, not sure what else to try. Sorry for the most likely sloppy code
If I were to input Hello and Test the output would be:
2, 5, Hest, 4, Test
Thanks
Code:
