ubase.getLastRecord (fnum)
|
| Params |
fnum is the number which identifies a uBASE database while it is open
|
| Returns |
The key for the last record in the indicated database (see Notes).
|
| Examples |
lastKey = ubase.getLastRecord (fnum)
key = ubase.getFirstRecord (fnum)
while key != lastKey
nextKey = ubase.getNextRecord (fnum, key)
ubase.deleteRecord (fnum, key)
key = nextKey
Deletes all records except the (arbitrary) last record from the database referenced by fnum.

| Errors |
An error is produced if uBASE is not running or if fnum does not identify an open database.
|
| Platform Notes |
uBASE runs only on Mac OS and is not a supported component of Frontier 5.0,
|
| Notes |
• The records in a uBASE database are ordered arbitrarily. ubase.getLastRecord can be part of a method for visiting each record in a database, or recognizing the last record.
• ubase.getLastRecord is not used as much as ubase.getFirstRecord
