# System Functions

GEP( ) | Return Even Parity String

## Format

GEP(string$[,ERR=stmtref])
Where:

string$ | Character string to convert to Even parity.
stmtref | Program line number or statement label to which to transfer control.

## 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 is 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.
