from Morris, In the U2 file you have decode as well as uncode. Do they have related functions, one doing the opposite of what the other does? Carl has often sent programs in text form which have to be decoded, but my question is how is the text version formulated in order for decode to work. Carl mentioned sometime back that in Xy4 you cannot use BX Q2 in all instances as BC XC must be used in certain cases for a program to work. What are those instances?
