SELECT
SELECT changes the current work area.
Syntax
SELECT <work area>/<alias>/(<expN>)
Argument
<work area> is a number between zero and 254 inclusive. Zero
designates the first available work area beginning with work area one.
<alias> is the name of an existing work area if there is a database
file open in that area. The first 10 work areas can be referred to
with the letters A through J. Specifying a non-existent alias produces
a run-time error.
(<expN>) is a numeric expression that evaluates to a number between
zero and 254. The expression must be bounded by opposing parentheses
to be evaluated.
Usage
Clipper supports 254 work areas. SELECTing 0 selects the first unused
area. Within each work area, you can open a database file and up to 15
index files. Each work area has a number of attributes which include:
Attribute Function

Work area number SELECT()
Database file ALIAS()
Index file(s) INDEXORD()/INDEXKEY()
Exclusivity FLOCK()/NETERR()
Filter condition
