• RAt(<cSearch>, <cTarget>) ➜ nPosition
  searches the string <cString> from right to left for the character string <cSearch> - NOTE: it is case-sensitive.

• RDDName() ➜ cRDD
  returns RDD name in use, RTE if no database is in use.

• RDDSetDefault([<cNewDefaultRDD>])➜ cPreviousDefaultRDD
  set the RDD to use. (there exist also, DBSetDriver([<cNewDefaultRDD>]) )

• ReadExit(<lToggle>) ➜ lCurrentState

• ReadInsert(<lToggle>) ➜lCurrentMode

• ReadKey() ➜ nReadkeyCode

• ReadModal(<aGetList>) ➜ NIL

• ReadVar() ➜ cVarName

• RecCount() ➜ nRecords
  (It is internally translated into Lastrec(). So, prefer to use LastRec() instead).

• RecNo() ➜ nRecord
  returns the record number of the current record in a work area. If no database is open in the work area, returns zero.

• RecSize() ➜ nBytes
  returns the record length, or number of bytes required to store a record in a database open in a work area. If no database is open in the work area, the return value is zero.

• Replicate( <cString>, <nCount> ) ➜ cRepeatedString
  returns a character string made up of <nCount> times the <String>.

• RestScreen( [<nTop>], [<nLeft>], [<nBottom>], [<nRight>], <cScreen> ) ➜ NIL

• Right(<cString>, <nCount>) ➜ cSubString
  the right-to-left counterpart of Left() function (refer..).

• RLock() ➜ lSuccess
  attempts to lock the focused record in current or aliased work area. Returns true if record lock is successful otherwise false.

• Round(<nNumber>, <nDecimals>) ➜ nRounded
  rounds off the value of <nNumber> to the number of decimal places specified by <nDecimals>. If the value of <nDecimals> is a negative number, the function will attempt to round <nNumber> in whole numbers. Digits from 5 through 9 will be rounded up (i.e to next greater value), while digits 1...4 will be rounded down (which, in other words, means they will be lost!).

• Row() ➜ nRow
  returns the current screen row.

• RTrim() ➜ cTrimString
  removes all trailing spaces from a string.
