Example
This example shows a typical use of the savepoint statement. During each loop of the program, a savepoint is declared, enabling the program to back out updates in the event of an error:
## begin transaction
saveindex = 0
loop until finished processing
saveindex = saveindex + 1
## savepoint saveindex
process data
if error condition then
## abort to saveindex
saveindex = saveindex - 1
end if
end loop
## end transaction
