The syntax taskname:parametername=soandso may be used to pass parameters to individual tasks called by emchain. See Sect. 3.5 for details. | ||||
Standard SAS parameters | ||||
Because emchain is a standalone Perl script, it does not deal with the standard SAS parameters (see taskmain) in exactly the same way as normal SAS tasks do:
