chain
1. vi. [orig. from BASIC's `CHAIN' statement] To hand off execution to a child or successor without going through the OS command interpreter that invoked it. The state of the parent program is lost and there is no returning to it. Though this facility used to be common on memory-limited micros and is still widely supported for backward compatibility, the jargon usage is semi-obsolescent; in particular, most Unix programmers will think of this as an exec. Oppose the more modern `subshell'.
2. n. A series of linked data areas within an operating system or application. `Chain rattling' is the process of repeatedly running through the linked data areas searching for one which is of interest to the executing program. The implication is that there is a very large number of links on the chain.

(1.) A part of the insignia of office. A chain of gold was placed about Joseph's neck (Gen. 41:42); and one was promised to Daniel (5:7). It is used as a symbol of sovereignty (Ezek. 16:11). The breast-plate of the high-priest was fastened to the ephod by golden chains (Ex. 39:17, 21). (2.) It was used as an ornament (Prov. 1:9; Cant. 1:10). The Midianites adorned the necks of their camels with chains (Judg. 8:21, 26). (3.) Chains were also used as fetters wherewith prisoners were bound (Judg. 16:21; 2 Sam. 3:34; 2 Kings 25:7; Jer. 39:7). Paul was in this manner bound to a Roman soldier (Acts 28:20; Eph. 6:20; 2 Tim. 1:16). Sometimes, for the sake of greater security, the prisoner was attached by two chains to two soldiers, as in the case of Peter (Acts 12:6).
