Its just bash topology... If your setting a variable and calling a command
after it, or doing anything on one line with another expression after it you
need to end the expression before starting another one, which is done with
the semi-colon ';'.

On the first one:

$ AAAA=aaa echo $AAAA

AAAA now looks like "aaa echo " unless AAAA already exists, and if so would
contain the variable contents after the "echo " bit...
