ChainDflt

The ChainDflt BRConfig.sys specification instructs the system to look for .BRO extensions before .BR extensions in file names. It can also be used with the Config ChainDflt command or within a program line using the Execute statement.

Comments and Examples

When you specify a program name in a CHAIN statement or LOAD command without indicating an extension, Business Rules! automatically assumes the extension is .BR unless you end the program name with a period, in which case Business Rules! assumes there is no extension. For example, if you specify PROG1, Business Rules! looks for a file with the name PROG1.BR. If it finds no file with that name, the system then looks for a file with the extension .BRO (an object file). The CHAINDFLT specification tells Business Rules! to look for a file with the .BRO extension before looking for one with the .BR extension.

CHAINDFLT O

Start-up Default

When no period and extension are specified in a file name, BR searches first for a file by the given name and a .BR extension. If no match occurs, it searches for a file by the given name and a .BRO extension.

Technical

1.) The CONFIG command can be used during program execution to override the BRConfig.sys file's CHAINDFLT specification.
