STRING(EXP) (STRING)

 Function
  Convert any expression to a string.

 Syntax
  STRING(exp)

   exp = Any expression.

 Return Type & Value
  STRING
  Returns exp formatted as a string.

 Remarks
  This function is immensely useful anytime you need to convert any
  expression to string format.  For example, to append an integer value to
  the end of a string without this function, you would need to assign the
  integer to a string and then append the temporary string to actual
  string.  This is because PPL's normal course of action when performing
  arithmetic with incompatible types is to convert everything to integer
  first.  With this function, you can accomplish the same function in one
  line of code with one expression because you are forcing addition of
  compatible types (strings).  Note that PPL does automatically convert
  incompatible types whenever possible, making this function unnecessary
  in many cases.  This function should only be necessary when trying to
  append the text representation of a non-string type to a string via the
  + operator.

 Examples
  INTEGER i
  STRING  s(5)
  FOR i = 1 to 5
    LET s(i) = "This is string "+STRING(i)
  NEXT

  STRING s
  LET s = STRING(ABORT())+" "+STRING(DATE())+" "+STRING(10)+" "
  LET s = s+STRING($10.00)+" "+STRING(TIME())
  PRINTLN s ' will print "0 10-31-67 10 $10.00 03:27:00" (or similar)
