Description
The CURSYNCNUM() function returns the current (last assigned) unique sequence number assigned to a row in the specified table. The CURSYNCNUM() function operates on the current workarea unless a numeric <workarea> or character <alias> is specified.
Each new row inserted into a table will be assigned a unique sequence number for that table. Even if the row is deleted later or if all the rows are deleted from the table, that number will not be issued again.
