sditfromsdit - Constructor

An sditerator from another sditerator.

Synopsis
sditfromsdit(sdit, selection)

Description
This constructor is equivalent to the select function.

Arguments

sdit	in	An sditerator
		Allowed:	sditerator `tool`
selection	in	Record describing any selections to do on opening
		Allowed:	Glish record
		Default:	[=]

Returns
sditerator tool

Example

  sdit := sditerator("a302_SP");
  selrec := [=];
  selrec.header := [=];
  selrec.header.source_name := "My source";
  sditSource := sditfromsdit(sdit,selrec)

The first line opens an existing data set. The rest make another sditerator by making and applying a selection record to the first iterator. In this example, sources matching the indicated name are selected. The resulting iterator will only have sdrecords which match that selection criteria.
