# CHARSHR()

Process each character in a string with bitwise SHIFT RIGHT operation

Syntax

  CHARSHR (<[@]cString>, <nBitsToSHR> ) --> cSHRString

Arguments

  <[@]cString> string to be processed <nBitsToSHR> number of bit positions to be shifted to the right

Returns

  <cSHRString> string with bitwise shifted right characters

Description

  The CHARSHR() function constructs a new string from the string passed as parameter. To do this, it performs a bitwise SHIFT RIGHT (SHR) operation to the characters of the string and places a character in the resulting string whose ASCII value equals to the result of that operation. Be aware that bits shifted out of the byte are lost. If you need a bit rotation, use the CHARRLR() function instead. If the string is passed by reference, the resulting string is stored in <cString>, too. By setting the CSETREF()-switch to .T., the return value can be omitted.

Examples

          ? charshr (chr(1)+chr(2)+chr(4)+chr(8)+chr(16)+chr(32)+chr(64)+chr(128), 3)
            --> chr(0)+chr(0)+chr(0)+chr(1)+chr(2)+chr(4)+chr(8)+chr(16)
    Tests
          charshr (chr(1)+chr(2)+chr(4)+chr(8)+chr(16)+chr(32)+chr(64)+chr(128), 3) == chr(0)+chr(0)+chr(0)+chr(1)+chr(2)+chr(4)+chr(8)+chr(16)
