+## 65493 $FF68 JSETBNK
+
+<span class="badge badge-info">Entry point for the SETBNK routine, currently at [$F73F](#F73F)</span>
+
+Establishes the current bank from which the data will be read or to which data will be written during load/save operation, as well as the bank where the filename for the I/O operations can be found.
+
+### Input
+
+* .A must contain the bank number for the data
+* .X must contain the bank number for the filename
+

+## 65493 $FFBA JSETLFS

+<span class="badge badge-info">Entry point for the SETLFS routine, currently at [$F7E8](#F7E8)</span>
+
+Assigns the logical file number, device number and secondary address for an I/O operation.
+
+### Input
+
+* .A must contain the logical file number
+* .X must contain the device number
+* .Y must contain the secondary address

+## 65493 $FFBD JSETNAM
+
+<span class="badge badge-info">Entry point for the SETNAM routine, currently at [$F731](#F731)</span>
+
+Assigns the length and the address of filename for a I/O operation
+
+### Input
+
+* .A must contain the length of the filename
+* .X must contain the lo-byte of the address of the first character of the filename
+* .T must contain the hi-byte of the address of the first character of the filename
+
+If no name is used for this operation, load .A with 0 so .X .Y are irrelevant.

+
+<span class="badge badge-info">Entry point for the LOAD routine, currently at [$F265](#F265)</span>
+
+Loads or verifies a program file from tape or disk into a specified area of memory.
+
+### Input
+
+* JSETLFS at [$FFBA](#FFBA) must be called to establish device number and the secondary address.
+* JSETNAM at [$FFBD](#FFBD) must be called to specify the length and the address of the filename
+* JSETBKN at [$FF68](#FF68) must be called to specify the bank number where the filename can be found and the bank where the data is to be loaded
+* .A must contain the operation type
+  * 0 for load
+  * !=0 for verify
+* if bit 0 of the secondary address is 0, the file will be loaded starting at the address specified in .X (lo-byte) and .Y registers (hi-byte). It's called a relocation load.
+* if bit 0 of the secondary address is 1, the file will be loaded at the address specified in the file itself. It's called an absolute load.
+
+### Output
+
+* Carry bit will be affected:
+  * clear if data has been loaded succesfully
+  * set in case of error or if RUN/STOP has been pressed and .A contains error code
+    * .A could be 4 (file not found), 8 (no name specified), 9 (illegal device number specificied), 16 (load extended over address $FEFF).
