Several MPE/iX commands can be used for KSAM files. KSAM files
can be deleted and renamed using the same commands used with standard
files. File attributes can be modified with a file equation.
Deleting a KSAM File |
 |
KSAM files can be deleted using the PURGE command. As with standard files, the file named
in the PURGE command is deleted. The accounts receivable file
can be deleted using the following command.
Renaming a KSAM File |
|
The RENAME command can be used to change the name of an existing
KSAM file. The file name specified in the command is deleted. The
parameters for the RENAME command are the same as for standard files. The
file name specified in the command is deleted. The first file name
is the current name of the KSAM file. The second file name is the
new name of the file.
RENAME ARMSTR.MGR, OLDMSTR.MGR. |
Modifying File Attributes |
|
The FILE command declares the file attributes to be used
when an existing file is opened. It can be used with KSAM files
as well as standard files. The FILE command's keywords (;KSAMXL, ;KSAM64, ;KEY, ;FIRSTREC, ;LANG, ;REUSE, ;NOREUSE, ;OPTMBLK and ;DEFBLK) perform the same functions as they do for the BUILD command.
The FILE command can be used to override system default
file specifications or specifications supplied with the HPFOPEN or FOPEN intrinsic. The new specifications remain in effect
for the entire job or session unless they are revoked by the RESET command or superseded by another FILE command.
