Guardian Programming Reference Summary for C—522630-001
11-24
144 Sets LU character set and double-byte character code
The param1 parameter must be omitted for function 144.
The param2 parameter must be omitted for function 144.
last-params[0]. Bit 0 = 0, no translation
=1SNAX does EBCDIC/ASCII translation
Bits 1-7 =IBM device type
1=IBM-3277
2=not 3277 or 3276
3=IBM-3276
Bits 8-15 = value of LU attribute ALLOWEDMIX
[1] Bits 0-7 = LU character set
0=ASCII (USASCII)
9=EBCDIC (IBM EBCDIC)
14 =KATAKANA EBCDIC
Bits 8-15 = double-byte character set
0=No DBCS
2=IBMKANJI
3=IBMMIXED
5=JEFKANJI
146 Queue waiters for disk file write
param1
= 0 disables the effect of param1
= 1 causes CONTROL 27 requests to be queued and completed one at a time;
otherwise all are completed by the first write.
The param2 parameter is not used with function 146.
SETMODE 146 remains in effect until the file has no more openers. When there
are no more openers, the effect of SETMODE 146 is lost and the next open must
repeat this SETMODE function.
149 Disk: Alternate key insertion locking
param1
= 0 no automatic locking (default): locking and unlocking during insertion is not
automatically performed.
= 1 automatic locking: writes of record with alternate keys are locked at the
beginning of insertion and unlocked after all associated alternate key record
insertions are complete. This prevents interference from programs
attempting concurrent update of the same record.
The param2 parameter must be zero, if supplied.
SETMODE 149 is not valid (nor needed) for audited files. For process pairs, the
mode needs to be set in the backup by CHECKSETMODE. If the file is a key-
sequenced file using the generic locks feature, the lock established by automatic
locking might not be released automatically at the end of the write processing.
