| ### Most Recent Operation Argument Name (_n) The _n variable holds the name or names used as an argument to the most recent control program operation. Most DCE control program objects take a name or a list of names as an argument. Those that don't include endpoint, attrlist, uuid, name, utc, and the miscellaneous dcecp commands dcecp_initInterp, login, logout, errtext, quit, resolve, and shell. The name is usually the third argument in a dcecp operation as shown in the following directory operation. dcecp> directory create /.:/sales/printers/text_printers dcecp> Once set, you can use $_n in subsequent operations in place of the name argument. For example, you could modify a directory attribute for the /.:/sales/printers/text_printers directory created in the preceding example. dcecp> directory mod $_n -change {CDS_Convergence low} dcecp> The _n variable can also hold a list of names, as when you perform a directory service operation on more than one name. For instance, you could create several directories and then decide to modify an attribute. dcecp> directory create { > /.:/sales/printers/text_printers > /.:/sales/printers/graphics_printers > /.:/sales/printers/colorgraphics_printers } dcecp> A subsequent directory service operation can simply use the _n variable in place of the name or list of names: dcecp> directory modify $_n -change {CDS_convergence high} dcecp> ###
