XFD_MAP tells the run time system to associate certain filenames with a particular XFD. This enables you to use one XFD for many different files. You can use XFD_MAP to add or replace the existing value, depending on the setting of the XFD_MAPS_RESETS configuration variable.
The XFD_MAP variable has this syntax:
XFD_MAP [pattern = base-xfd-name] ...
where pattern consists of any valid filename characters and may include "*" or "?". These two characters have special meanings in the pattern:
|*||matches any number of characters|
|?||matches a single occurrence of any character|
|CUST????||matches CUST0001 and CUSTOMER;
does not match CUST001 or CUST00001
|CUST*||matches all of the above|
|CUST*1||matches CUST001 and CUST0001 and CUST00001;
does not match CUSTOMER
does not match CUST001 or CUST0001
Note that XFD_MAP cannot be read from the ACCEPT FROM ENVIRONMENT statement.
