:writeVar  StrVar
::
:: Writes the value of variable StrVar to stdout without a terminating
:: carriage return or line feed.
::
:: The routine relies on variables defined by :writeInitialize. If the
:: variables are not yet defined, then it calls :writeInitialize to
:: temporarily define them. Performance can be improved by explicitly
