Annex C: Record Pointer Management

• Annex C.1 Case 1
• Annex C.2 Case 2

Annex C.1 Case 1

Case 1 deals with the first command issued after a select function (either explicit or implicit). The current record pointer (CP) is undefined.

Command READ RECORDS	Record in response	Position of CP after command
Next (id=aa)	First with id=aa If not found, then error	Record read Undefined
Previous (id=bb)	Last with id=bb If not found, then error	Record read Undefined
First (id=cc)	First with id=cc If not found, then error	Record read Undefined
Last (id=dd)	Last with id=dd If not found, then error	Record read Undefined
Next (id=00)	First	Record read
Previous (id=00)	Last	Record read
First (id=00)	First	Record read
Last (id=00)	Last	Record read
Record #00	Error	Undefined
Record #EE	#EE If not found, then error	Undefined
P1='00', P2='xxxx x101'	Error	Undefined
P1='00', P2='xxxx x110'	Error	Undefined
#jj, P2='xxxx x101'	#jj to last If #jj not found, then error	Undefined
#kk, P2='xxxx x110'	Last to #kk If #kk not found, then error	Undefined

Annex C.2 Case 2

Command READ RECORDS	Record in response	Position of CP after command
Next (id=aa)	Next with id=aa If no next, then error	Record read Unchanged
Previous (id=bb)	Previous with id=bb If not found, then error	Record read Unchanged
First (id=cc)	First with id=cc If not found, then error	Record read Unchanged
Last (id=dd)	Last with id=dd If not found, then error	Record read Unchanged
Next (id=00)	CP+1 If CP=last, then error	Previous CP+1 Unchanged
Previous (id=00)	CP-1 If CP=first, then error	Previous CP-1 Unachanged
First (id=00)	First	First record
Last (id=00)	Last	Last record
Record #00	CP	Unchanged
Record #EE	#EE If not found, then error	Unchanged
P1='00', P2='xxxx x101'	CP to last	Unchanged
P1='00', P2='xxxx x110'	Last to CP	Unchanged
#jj, P2='xxxx x101'	#jj to last If #jj not found, then error	Unchanged
#kk, P2='xxxx x110'	Last to #kk If #kk not found, then error	Unchanged
