Syntax

g{skip.segments} delimiter get.segments

Note: The implied spaces between the arguments in the syntax definition are for visual clarity only and are not allowed.

`skip.segments`	Specifies the number of delimited groups to skip before performing the extraction. If omitted, zero is assumed, and extraction occurs from the beginning of the value.
`delimiter`	Any single printable character excluding integers and these characters:
	_	segment mark (SM)
	^	attribute mark (AM)
	]	value mark (VM)
	\	subvalue mark (SVM)
`get.segments`	Specifies the number of contiguous groups to extract from the value.

The example below illustrates the results obtained from various combinations of the g code if the value being processed was the string:

ca*92714*1000
g*1   ca
g0*1  ca
g*3   ca*92714*1000
g1*2  92714*1000
g2*1  1000
g2*2  1000
g3*1  (null)
