Can you help is by testing?
E.g. customer.dbf opened with alias CUST
Code: Select all | Expand
? CUST->CITY
CUST->CITY := "CHANGED"
? CUST->CITY
CUST->( dbRollBack() )
? CUST->CITY

E.g. customer.dbf opened with alias CUSTNote: dbRollBak() works only when the Record Pointer is not moved and DBCOMMIT() is not executed alreadyCode: Select all | Expand
? CUST->CITY CUST->CITY := "CHANGED" ? CUST->CITY CUST->( dbRollBack() ) ? CUST->CITY
I will make the case:
Code: Select all | Expand
? CUST->CITY
CUST->CITY := "CHANGED"
? CUST->CITY
CUTS->( DbUnlock() )
// do other process...
CUST->( dbRollBack() )
? CUST->CITY
if after making the change to "CHANGED" and doing the dbunlock, if before the dbrollback() another user modifies the value of CUST->CITY by "OTHER USER"
when the rollback() is performed, what value will CUST->CITY finally have, "ORIGINAL" or "OTHER USER" ?

After doing unlock also, dbrollback does not work
Rollback works before (1) moving record pointer (2) before commit and also (3) before unlock.
This is useful for making modifications in more than one dbf and ensure that either all changes are committed or rolledback.
