CABSAD$, CRELAD$–Addressing Routines
If both of the parameters file-name and sector-addr are omitted on the call, then the
routine uses the value in registers A0 and A1 for file-name and the value in register A2
for sector-addr.
Error Return
The error return is identical to a CRELAD$ error return.
6.2.3. CBN$–Convert BDI to Symbolic Bank Name
CBN$ determines the symbolic bank name that corresponds to the given BDI and
returns it in registers A0 and A1 in Fieldata format, left-justified, and space-filled.
Calling Format
C$RELAD[,t] ‘CBN$’[,bdi] [pkt-addr]
error return
normal return
Parameters
t
CBN$
bdi
See 6.1.
CBN$ is the function code that determines which of the absolute addressing
routines is called by C$RELAD. It must be enclosed by apostrophes.
bank descriptor index that is to be translated into a bank name. This parameter may
be included as a number, as a tag that has been equated to a number, or as the
address of a word that contains the value of the number.
If parameter bdi is omitted, then the value in register A0 is used as the BDI.
pkt-addr
See 6.1.
Error Return
If A0 = 0 at the error return, the BDI is out of range or refers to a common bank. If A0 ≠
0, an I/O error occurred and the registers contain the same values as for a CRELAD$ I/O
error.
