DEFCNTX and APDFCNTX parameters
Default file or group context
Default file or group context when APSY command issued
- Default value
- Parameter type
- Where set
- Related products
- Model 204 V7.4 or earlier
These parameters provide information about the default file or group context, that is, which file or group is used when a file-based operation is performed without the qualification provided by the IN clause.
- DEFCNTX returns the current default context of the thread:
the most recent successful OPEN statement, OPEN command, or DEFAULT command.
The first word or two returned by DEFCNTX is the type of context:
TEMP GROUP, or
PERM GROUP. The last word returned by DEFCNTX is the name of the file or group.
If there is no default context, the value of DEFCNTX is the null string.
APDFCNTX shows the default context when the Apsy command was issued.
Note: If the default context when an Apsy command was issued is the same as one of the files or groups in the Apsy's definition, APDFCNTX returns the null string.
The first word or two returned by APDFCNTX is the type of context:
TEMP GROUP, or
PERM GROUP. The last word returned by APDFCNTX is the name of the file or group.
If there is no default context, the value of APDFCNTX is the null string.
DEFCNTX and APDFCNTX are very similar to the CURFILE parameter, with these differences:
- CURFILE returns a null string if the default context is a group.
- CURFILE is affected by the IN clause prior to a Begin command and can be affected by the In clause prior to many SOUL statements. DEFCNTX and APDFCNTX are not affected by (either form of) the IN clause.
