In order to change a certain object's setting with REXX, use the following RexxUtil function:
rc = SysSetObjectData(name, setup)

with:

name being the object you wish to change (referenced either by a full path specification or an object ID, such as <WP_DESKTOP>);

setup being one of the WPS setup strings, which always have a keyword=data syntax. You can combine several settings by separating them with semicola (;).

Example:

  if SysSetObjectData(directory(),"NOMOVE=YES;DEFAULTVIEW=ICON") then
    Say "Settings changed!"

This will change the folder settings for the current directory, which is useful for scripts called by XFolder, which have the intended directory already changed to.

See the &os2; REXX Reference for details.
