| Syntax |
ubase.getFirstRecord (fnum)
|
| Params |
fnum is the number which identifies a uBASE database while it is open
|
| Returns |
The key for the first record in the indicated database (see Notes).
|
| Examples |
key = ubase.getFirstRecord (fnum)
for i = 1 to ubase.countRecords (fnum)
nextKey = ubase.getNextRecord (fnum, key)
ubase.deleteRecord (fnum, key)
key = nextKey
Deletes all the records from the database referenced by fnum (which may not be a good idea!)
|
| 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.getFirstRecord is part of a method for visiting each record in a database.
• If key refers to the last record in the database, or to a record which does not exist, the empty string is returned.
