I haven't been able to find anything about this in Help. Can somebody tell me how "Save as SGML" works in Arbortext Editor or point to some documentation that does? I have temporarily lost access to the Programmers Reference Guide so I can't look there, if there is anything there. I can get it to work with the axdocbook demo.xml file and it works pretty well. Other XML files have the menu item grayed out. I presume that the target SGML DTD/doctype is defined somewhere, but I can't find out where. The menu.cf file shows the command for the Save as SGML menu selection to be "FileSaveAsSGML" with a qualifier of "!doc_dtd_not_defined()". I presume that the target SGML DTD is defined somewhere, but again I don't know where.
If all this is in the Programmer's Reference Guide then that is enough of an answer.
I know that asking to "Save as SGML" today is like asking for a way to make my polio vaccine ineffective or something, but we need to be able to do this somehow.
There isn't a lot in the help center. However, the function doc_dtd_not_defined is in the help. Topic 10018. The save as help is 9132 (if you can get to help by typing in the help ####).
Try typing 'eval doc_dtd_not_defined()' on the command line and see if you get a return of '0'. If not that seems to be saying Epic cannot find a DTD/Schema (and I tried this with files using both DTD and Schema in the DOCTYPE header both files returned the '0').
There is also a 'doc_dtd_not_found()' function, help 2091 that is pretty similar.
