Purpose
Function to return the current or specified cursor/workarea number
Syntax
SELECT([<alias> | <expN>])
See Also
ALIAS(), DBF(), SELECT, SELECT (SQL), USE, WORKAREA()
Description
The SELECT() function returns the number of the currently selected workarea. If the optional <alias> is specified, the SELECT() function returns the workarea number for that alias. If the <alias> specified does not exist, the SELECT() function will return a 0. Specifying 0 as <expN> returns the current cursor/workarea number, specifying 1 as <expN> returns the highest available empty cursor/workarea number.
Example
close all ? select() 1 use prefixes in 3 ? select ("prefixes") 3 ? select(0) 3 ? select(1) 100 // Another Example // to access each open workarea m_count=0 select 1 do while not empty(alias()) m_count = m->m_count + reccount() select select() + 1 enddo dialog box "Total records in all tables is &m_count"
