Answer 2

recall --> recalls records marked for deletion
i.e.
dele all (delets all records)
recall all (recalls all records)

pack --> physically removes the record from dbf marked for deletion
i.e.
use customer
dele all
pack

nothing will be left in the dbf just like a dull brain

replace --> u can update values

replace all basic with 10000

replaces all records with 10000 in basic field

locate ---> locate finds a record
i.e.
use customer
locate for city = 'SA'

the record pointer moves the record wherre 'SA' is found in city
continue
will move to the next matching record

if no matching record found then end of locate scope will come

list

lists out all the records of the currently opened dbf

list off

lists out all the records of the currently opened dbf without recno()

display

displays the current record

there are so many commands in foxpro.

also u can give condition in the above commands

i.e. u can say dele for name = 'SMART'


u are so sweet. u are asking entire foxpro to be taught in yahoo answers.
