GEP( ) Function
            Return Even Parity String
Format
GEP(string$[,ERR=stmtref])
Where:
string$
Character string to convert to Even parity.
stmtref
Program line number or label to transfer control to.
Returns
Even parity value of string.
Description
The GEP( ) function converts and returns the character string expression in Even
parity. This function is typically used when dealing with communication lines. It's
not normally used by the operating system since the standard communications
drivers handle the generation of parity.
The number of one-bits in each byte of the character string determines the parity of
data. Even parity data always has an even number of one-bits in each byte of data.
