XFD_PREFIX configuration variable

When this ACUFH configuration variable is assigned a value, it is used to locate the XFD file, and the variable XFD_DIRECTORY is ignored. XFD_PREFIX enables you to define a specific series of directories to search for XFD files, rather than indicating only one. The run-time system searches each directory in the order specified until an XFD file matching the name of the desired file is found and then assumes that is the correct file.

Therefore, when using the XFD_PREFIX variable, be aware that the run-time system:

You can specify a directory path that contains embedded spaces if you surround the path with quotation marks. You separate entries using a semi-colon (;). For example:

XFD_PREFIX C:\"Sales Data";C:\Customers 

You can specify up to 4096 characters for this variable.


The default for XFD_PREFIX is empty. If this variable is set to any other value, the ACUFH configuration variable XFD_DIRECTORY (in which you specify only one directory) is ignored.
