+ *  $DESCRIPTION$
+ *      READVAR() is set inside a READ or MENU TO command to hold the
+ *      uppercase name of the GET / MENU TO variable, and re-set back to old
+ *      value when those commands finished. You should not normally set a
+ *      variable name but rather use it to retrieve the name of a GET
+ *      variable when executing a VALID or WHEN clause, or during SET KEY
+ *      execution and you are inside a READ or MENU TO.
+ *  $EXAMPLES$
+ *      // display a menu, press F1 to view the MENU TO variable name
+ *      CLS
+ *      @ 1, 10 PROMPT "blood sucking insect that infect beds   "

+ *  $STATUS$
+ *  $COMPLIANCE$
+ *      READVAR() works exactly like CA-Clipper's READKEY(), note however,
+ *      that the <cVarName> parameter is not documented and used internally
+ *      by CA-Clipper.

+ *  $ARGUMENTS$
+ *      <nFunctionKey> is a number in the range 1..40 that represent the
+ *      function key to be assigned.
+ *
+ *      <cString> is a character string to set. If <cString> is not

+ *  $RETURNS$
+ *      __SetFunction() always return NIL.
+ *  $DESCRIPTION$
+ *      __SetFunction() assign a character string with a function key, when
+ *      this function key is pressed, the keyboard is stuffed with this
+ *      character string. __SetFunction() has the effect of clearing any
