An installation batch file written in the REXX language performs the same operations but uses the following REXX-language utility functions:

REXX Functions

Workplace Shell Methods
SysCreateObject
WinCreateObject
SysRegisterObjectClass
WinRegisterObjectClass
SysDeRegisterObjectClass
WinDeregisterObjectClass

An example of an installation batch file written using the REXX-language utility methods is shown in the following sample code:

/* Register a Workplace Shell class and create an instance */
/* Load the REXX utility functions */
call RxFuncAdd 'SysLoadFuncs', 'RexxUtil', 'SysLoadFuncs'
call SysLoadFuncs

/* Register the class with the Workplace Shell */
if SysRegisterObjectClass("NewObjectClass", "NEWDLL") then
  say 'Class Registration successfully completed for the NewObject'

/* Create an instance of the object */
if SysCreateObject("NewObjectClass",
                   "A New Object",
                   "<WP_Desktop>",
                   "OBJECTID=<A New Object>") then
     say 'A New Object successfully created and placed on Desktop'
