HASHWF ANNOUNCE * Description
*
* Calling sequence (standard calling conventions)
* Parm 1: Byte string to be hashed
* Parm 2: Integer (fullword) - byte string length
* Parm 3: Integer (fullword) - Returned hash value (0 to 2**31-1)
*
* Uses 6 or 7 machine instructions per byte.
*
HASHWF ASSEMBLE * Assembler source, documentation
HASHWF TEXT * Text (Assembler object) deck
*
* REXX interface providing a REXX HASH function.
*
* Example: n = hash(string, table_size);
*
* The first argument is any string. The second argument is the size of
* the hash table. The result will be from 1 to the size. If the second
* argument is omitted, the returned value will be from 0 to (2**31)-1.
*
* NOTE: if the text decks are loaded and a new module is generated by
* using GENMOD, be sure to specify the RLDSAVE option for LOAD.
*
RXHASH ASSEMBLE * REXX interface assembler source
RXHASH TEXT * REXX interface object deck
RXHASH MODULE * REXX interface module
*
* C source version
*
* Function invocation (common C conventions)
* Parm: Char string to be hashed, terminated by a X'00' byte.
* Returns: Long Int (fullword) - Hash value (0 to 2**31-1)
*
* No object deck for the C source is provided
*
HASHWF C * C/370 Source version
*
* The RISC/6000 version is a good performance (8 cycle loop) version.
* It includes ASCII case folding to allow insensitive searchs on a
* single hash chain. Parms: string, length. Result same as above.
*
HASHWF C6000 * RISC/6000 AIX version
