# @FUNCTION: print_var_with_spaces()
#
# Print a defined variable giving its name then value printed with spaces
# instead of ``';'``.
#
# Usage::
#
#    print_var_with_spaces(<varName>  <printedVarInOut>)
#
# Prints the variable as::
#
#    <varName>: <ele0> <ele1> ...
#
# If ``$<printedVarInOut>`` is ``TRUE`` on input, then the variable is not
# touched. If however, the variable ``$<printedVarInOut>`` is not ``TRUE`` on
# input, then it is set to ``TRUE`` on output.
