A call to CKCLOSE terminates file processing for the specified KSAM
file. CALL "CKCLOSE" USING filetable, status |
When processing is completed, a KSAM file should be closed
with a call to CKCLOSE. No further processing is allowed on the file
until a CKOPEN procedure call opens the file. CKCLOSE can be executed only for a file that is open. Parameters | |
- filetable
An 8 halfword record containing: the name of the
file, its input/output type, access mode, the file number given
the file when it was last opened, and a code indicating whether
the previous operation on the file was successful and if so what
it was. (Refer to Filetable Parameter discussion earlier in this
section.) - status
One-halfword (two 8-bit characters) set to a pair
of values upon completion of the call to CKCLOSE. It indicates whether or not the file was successfully closed
and if not, why not. The left character is set to 0 if CKCLOSE is successful, to 9 if not. The right character
is set to 0 if CKCLOSE is successful, to the file system error code if
not. (Refer to Status Parameter discussion earlier in this section.)
Operation Notes | |
Upon successful completion of CKCLOSE, the file identified by filetable is no longer available for processing. Note that
a KSAM file can be closed and then reopened in order to specify
a different access mode or input/output type.
FINISH.
CALL "CKCLOSE" USING FILETABLE, STAT.
IF STATUS-KEY-1 = "9" THEN
CALL "CKERROR" USING STAT, RESULT
DISPLAY "CKCLOSE ERROR NO. ", RESULT;
ELSE DISPLAY "CKCLOSE SUCCESSFUL". |
