L OF THE VLIR RECORDS, APPENDED END-TO-E
ND, STARTING WITH THE FIRST EXISTING REC
ORD (USUALLY RECORD #0). ADDING UP ALL O
F THE "NUMBER OF BLOCKS" ENTRIES IN THE
THIRD BLOCK WILL GIVE YOU THE TOTAL NUMB
ER OF BLOCK WHICH REMAIN...THUS IF THE V
LIR FILE HAS TWO BLOCKS IN RECORD #0, ON
E BLOCK IN RECORD #4, AND NULL POINTERS
(NO BLOCKS) FOR ALL OTHER RECORDS, THEN
THE RESULTING COMMODORE SEQ FILE WILL CO
NTAIN: ..BLOCK 1: DIRECTORY ENTRY .BLOC
K 2: FILE HEADER .BLOCK 3: BLOCKS/BYTE
S PER RECORD . TABLE .BLOCK 4:
BLOCK #1 OF RECORD #0 .BLOCK 5: BLOCK
#2 OF RECORD #0 .BLOCK 6: BLOCK #1 OF R
ECORD #4..NOTE THAT THE CONVERSION PROCE
SS DOES NOT CREATE A NEW FILE, IT SIMPLY
MODIFIES THE EXISTING GEOS VLIR OR SEQ
FILE SO THAT IT CONFORMS TO THE FORMAT O
F A COMMODORE SEQ FILE. USING A GEOS VLI
R FILE AS AN EXAMPLE, THIS PROCESS INVOL
VES:..1) CREATING A NEW BLOCK TO CONTAIN
THE FILE'S DIRECTORY ENTRY, CHANGING TH
E EXISTING DIRECTORY ENTRY SO THAT THE P
OINTER TO THE FILE'S FIRST BLOCK NOW POI
NTS TO THIS NEW BLOCK. THE NTS POINTER I
N THIS NEW BLOCK WILL POINT TO THE FILE'
S EXISTING HEADER BLOCK...2) CHANGING TH
E NTS POINTER IN THE BLOCK CONTAINING TH
E FILE HEADER SO THAT IT POINTS TO THE F
ILE'S INDEX TABLE BLOCK...3) CHANGING TH
E FILE'S INDEX TABLE BLOCK SO THAT IT HA
S ACCURATE "NUMBER OF BLOCKS/BYTES" INFO
RMATION FOR EACH RECORD. ALSO, THE NTS P
OINTER IN THIS BLOCK IS ALTERED TO POINT
TO THE FIRST BLOCK OF THE FIRST RECORD
WHICH EXISTS...4) CHANGING THE NTS POINT
ERS IN THE FIRST AND LAST BLOCKS OF EACH
RECORD, SO THAT THE RECORDS ARE APPENDE
D INTO A STRING OF BLOCKS...ALSO, THINK
ABOUT THE REVERSE PROCESS. CONVERT WILL
TAKE A COMMODORE SEQ FILE WHICH COMPLETE
LY DEFINES A GEOS VLIR OR SEQ FILE AND W
ILL CONVERT IT TO THE CORRECT STRUCTURE.
SOFTWARE DEVELOPERS MAY FIND THIS USEFU
L; IF YOU ARE USING A STANDARD COMMODORE
ASSEMBLER WHICH CREATES COMMODORE SEQ F
ILES, THEN IF THE DATA IS SET UP RIGHT,
CONVERT CAN BE USED TO TURN THE COMMODOR
E SEQ FILE INTO A RUNNABLE GEOS VLIR OR
SEQ APPLICATION! WE WILL POST A NOTE IN
THE FUTURE ABOUT HOW TO DO THIS...APPEND
IX C (P432) CORRECTIONS.....THANKS FOR J
PP AND MIKET22 FOR ALERTING ME TO SOME E
RRORS ON P432 OF THE PROG REF MANUAL:..D
ONEWITHIO SHOULD READ $C25F COPYSTRING S
HOULD READ $C265..DESK ACCESSORIES IN AP
PLICATIONS..THIS NOTE IS FOR PEOPLE WRIT
ING APPLICATIONS WHICH ALLOW THE USER TO
RUN DESK ACCESSORIES...MOST GEOS APPLIC
ATIONS THAT HAVE BEEN WRITTEN ARE VLIR M
ODULE SWAPPING APPLICATIONS, AND SO THE
DISK CONTAINING THE APPLICATION MUST ALW
AYS BE IN ONE OF THE ACTIVE DRIVES. THE
CONVENTION FOR PLACEMENT OF DESK ACCESSO
RIES IS THAT THEY MUST BE ON THE APPLICA
TION DISK. THIS WAY, THE DAS WHICH APPEA
R IN THE APPLICATION'S GEOS MENU ARE ALW
AYS ACCESSIBLE. APPLICATIONS OF THIS TYP
E WHICH ALLOW THE USER TO LOAD DATA FROM
THE OTHER DRIVE MUST KEEP TRACK OF WHIC
H DRIVE IS THE APPLICATION DRIVE. FOR EX
AMPLE, ASSUME THE APPLICATION DISK IS IN
DRIVE A AND THE DATA DISK IS IN DRIVE B
. WHEN THE APPLICATION IS RUN FROM THE D
ESKTOP, ONE OF THE FIRST THINGS IT DOES
IS TO READ THE DISK'S DIRECTORY, GRABBIN
G THE NAMES OF THE DAS ON THAT DISK AND
STUFFING THEM INTO THE GEOS MENU DEFINIT
ION TABLE. THEN WHEN THE USER HAS OPENED
A DATAFILE WHICH IS ON THE DISK IN DRIV
E B, AND HE SELECTS A DA FROM THE MENU,
THE APPLICATION MUST CALL OPENDISK TO OP
EN DRIVE A TO RUN THE DA. WHEN THE DA FI
NISHES, THE APPLICATION MUST CALL OPENDI
SK TO RE-OPEN THE DATA DISK IN DRIVE B.
IF THE SYSTEM ONLY HAS ONE DRIVE, THEN T
HERE IS NO PROBLEM BECAUSE THE DISK IN D
RIVE A CONTAINS THE APPLICATION, THE DAS
, AND THE DATAFILE; NO DRIVE SWITCHING I
S REQUIRED WHEN RUNNING DAS...FOR APPLIC
ATIONS WHICH RUN ENTIRELY RESIDENT IN ME
MORY (NEVER SWAPPING MODULES) YOU MIGHT
BE TEMPTED TO ALLOW THE USER TO REMOVE T
HE DISK ON A ONE-DRIVE SYSTEM AND INSERT
A DIFFERENT DATA DISK. APPLICATIONS SUC
H AS THE ICON EDITOR ALLOW THIS. BUT BE
SURE THAT IF YOU ALLOW THIS CAPABILITY,
THAT WHEN THE DA IS SELECTED AND THE APP
LICATION DISK HAS BEEN REMOVED, YOU MUST
EITHER 1) NOT ALLOW THE DA TO RUN, OR 2
) PUT UP A DIALOG BOX REQUESTING THAT TH
E APPLICATION DISK BE INSERTED SO THAT T
HE DA CAN RUN...MACROS FOR REFERENCE MAN
