It is, but since we have functions and procedures, we don't need the gosub,
except as something which disregards the returns, if any. The Basic gosub
translation to Eu might be difficult, given the scope of the function is the
same as the calling code block. I have arguements for and against sharing
scope with gosubs, but i have made good use of nesting procedures and
functions inside other procedures and functions, to share scope of non-global
vars. This is generally easily solved in Eu with included files though.
