Setting irregular index ranges

 

Syntax

BD>indexvec : C=D

where C is an alphabetic character representing an index, and where D is the name of a data-carrier.

The syntax for the INDEXVEC:  command defines the name of an index, C, and a range of values to be associated with it. To use this syntax, it is necessary to have created a data-carrier D of length k, with k data cases , beforehand. The intention is to replace the character C successively by the integers .

The command is used to vary the indices of quantities referenced in COBUILD:  and ITADJUST:  commands. An index can be overwritten - if an error occurs during re-definition, the former value is retained. The values used for indices should round to positive integers no larger than 32767. Index definitions can be deleted with the XINDEX:  command. When, for whatever reason, a data carrier is deleted or overwritten, and if it is also associated with an index, the index is deleted.

For example, suppose that you wish to construct (using the COBUILD:  command) the elements for , , and . Assuming that appropriate functional beliefs have been specified, the following code example shows how we could proceed.

index: j=1,1,4

data: <tempa>3

1 7 8

indexvec: i=tempa

data: <tempb>4

2 17 19 24

indexvec: k=tempb

cobuild: a.i.j.k

The example shows the irregular patterns being stored as the data-carriers and respectively, and then associated with indices respectively via the INDEXVEC:  command. We define the index j via the INDEX:  command as it is associated with a regular pattern.
