Purpose
Function to return the current 'SEQNO' value
Syntax
CURRSEQNO([<workarea | alias>])
See Also
LASTSEQNO(), SEQNO(), SET SEQNO, ZAP
Description
The CURRSEQNO() function returns the current 'SEQNO' value. The SEQNO value is a unique sequence number generated on a per table basis. The CURRSEQNO() function differs from the SEQNO() function in that CURRSEQNO() returns the current sequence number for a table and SEQNO() increases the current sequence number by one and then returns the value. Including the optional <workarea | alias> parameter will cause the CURRSEQNO() function to operate on the specified table. If there is no active table the CURRSEQNO() function will return 0.
A ZAP operation will reset the sequence number to 0. The sequence number of a table can be reset with the command SET SEQNO TO <expN>.
The SET SEQNO command and CURRSEQNO() and SEQNO() functions are only supported for Recital tables.
The CURRSEQNO() function is synonymous with the LASTSEQNO() function.
Example
use newtable ? seqno() 1 ? seqno() 2 ? currseqno() 2 ? currseqno() 2 set seqno to 0 ? currseqno() 0 ? seqno() 1
Products
