Help for ZIPCOL

PURPOSE

	ZIPCOL is used to enter data into an existing IBIS interface file.
Data can be transferred to the interface file from another interface file,
data cards, or both sources. Data is entered by matching keys between the
interface file and the data sources. Pre-sorting of the interface file and
the data sources is required. The size of the interface file is not changed
by operation of ZIPCOL.

TAE COMMAND LINE FORMAT

	zipcol INP=(A,B) INCOL=(X1,X2,X3,...XK) OUTCOL=(Y1,Y2,Y3,...YK)
		NULL=(C1,C2,...CN) FILE=(D1,D2,D3,...DK,E1,E2,...EN)

	Where A is the IBIS interface file being modified and B is a
secondary input interface file.

EXAMPLE

	zipcol INP=(INT1,INT2) INCOL=(28,27) OUTCOL=(1,2,3,4)
		FILE=(6,7,8,9,10,11) NULL=(0,0,0,0)

	In this example, columns 6, 7, from INT2 will be used to match
columns 28, 27 from INT1. If a match is made to columns 6,7 of INT2,
then columns 8, 9, 10, 11 from INT2 will be placed in columns 1, 2, 3, 4
of INT1. If no match is found zeros will be placed in columns 1, 2, 3, 4
of INT1.

OPERATION

	ZIPCOL operation is as follows. Each key in the first file is checked
against each key in the second. If a match is found, data is transferred from
the second file to the first file. Resultant information is written in an
update mode to the interface file being modified.
