BDT Command Prefix

The prefix tells the system that the command is a BDT command. The prefix you use depends on the type of console you are using (MCS, JES3, or TSO), and whether your system programmer has created short-cuts (such as PF keys). For a listing of the IBM-defined prefixes, see Table 1.

Table 1. IBM-Defined Prefixes
Type of Console	Prefix in a Single-BDT Complex	Prefix in a Poly-BDT Complex
MCS	bdt-char or BDT or F [bdt-proc.]bdt-id	Same
JES3	*S,BDT	*S,BDT,SY(node-name)
TSO	BDT	BDT SY(node-name)

bdt-char is a special character (such as /) that routes the command directly to a specific system. Do not use a delimiter (a comma or a blank) after bdt-char. For information on defining bdt-char, see z/OS BDT Installation.
bdt-proc is the name of the cataloged procedure in SYS1.PROCLIB that is used to start BDT. It is optional.
bdt-id is the installation-defined identifier of BDT.
SY(node-name) is the system parameter that indicates to which BDT subsystem the command should go. Include the parentheses as shown.

Note: At an MCS console, the bdt-char prefix and the “BDT” prefix invoke BDT user exit routine BDTUX28. The “F” prefix does not.

Some valid specifications for a command using the TSO prefix are listed below.
