APTTAGTPLDIR — Specifying the Path for the Tag Template Directory
Specifies a path list to the location of tag templates. You can use the %D and %Hsymbolic parameters in the path list.
Example
set APTTAGTPLDIR=c:\tagtpldir1;%D;d:\tagtpldir2
You can also use the Arbortext-path\custom\tagtemplates subdirectory to automatically make tag templates available when Arbortext Editor starts.
You can put custom tag templates you want associated with a particular document type into a custom\doctypes\doctype\tagtemplates directory or in the original location of the document type's doctype\tagtemplates directory.
You can also specify alternate or additional locations for your tag templates directory via the document type’s DCF file. Refer to Specifying an alternate location for a tag templates directory for information.
