Morse code translator

Turn the words on the command line into Morse code. The starter already holds the code for every letter: 26 strings, and a table morse of 26 pointers to them in alphabet order, eight bytes each (.dword). The args box holds hello world. Change it and press run to try other words; check always uses hello world.

For each word from argv[1] on, walk its bytes with ldrbLoad byte into Wt. until the zero byte that ends it. Turn each letter into a table index ('a' is 0, 'z' is 25, and a capital counts the same as its lower-case letter), load the pointer at that index, and print the string it points to with %s. Anything that is not a letter prints ?.

Spacing matters, because the output is compared exactly:

• one space between the letters of a word
• / between words
• a newline at the very end
• with no words at all, print nothing to send on its own line and return 1 from main

So hello world prints .... . .-.. .-.. --- / .-- --- .-. .-.. -...

What is checked

• the Morse line for hello world (the args shown in the specification), and for more arguments you cannot see
• the exit status (0 after a message, 1 with nothing to send)
• the words are read byte by byte (ldrbLoad byte into Wt.)
