ABL Reference

Interprets one or more consecutive bits in an integer variable or field as an ABL integer value and returns that value.

GET-BITS( source , position , numbits ) |

source

An ABL 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, the AVM returns the Unknown value (?). If position is less than 1, the AVM generates a run-time 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, the AVM generates a run-time error.

This function can return a value greater than 32 bits if source is an INT64.
