Progress 4GL Reference

GET-BITS function

Interprets one or more consecutive bits in an integer as a Progress INTEGER value and returns that value.

Syntax

GET-BITS( source , position , numbits )

source

A Progress integer variable.

position

A variable or expression that returns an integer. This parameter designates the position of the lowest-order bit of the bits that are to be interpreted as an integer. Bits are numbered from 1 through the length of an integer; with 1 being the low-order bit. If position is greater than the length of an INTEGER, Progress returns the Unknown value (?). If position is less than 1, Progress generates a runtime error.

numbits

The number of bits to examine when generating the return value. If position plus numbits is greater than the length of an integer plus 1, Progress generates a runtime error.
