XFD_PREFIX configuration variable

When this ACUFH configuration file 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:

• Searches each named directory and not its subdirectories
• Stops searching once a matching file name is found, even if other files of the same name are located in a different directory later in the series
• Does not validate that the file specifications (such as key or record size parameters) of the XFD file match those in the COBOL program. Be sure the correct file you want to use is in the path specified

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.
