- Example: scan handler looking for AutoDoc nodes. Scan handlers are plain
- functions (LoadSeg'ed by GED): no standard C startup code, no library calls.
- This handler is faster than GoldED's built in AutoDoc handler since it simply
- looks for formfeeds. Won't work with all AutoDocs though Commodore's AutoDocs
- are handled properly.
-
- DICE C:
-
- dcc ADoc.c -// -l0 -md -mRR -o ram:ADoc
