Daniel, Thanks for the help. I'm attaching a modified copy of fixgram myself. This version runs on my system, produces the expected output, and does _not_ cause make to generate a return code of 139. Please let me know if it works on your platform, and if it does, please integrate it into the source tree.
Essentially there are two changes. The first one is an added "positioning" command to set the insertion point for the three lines that were ending up at line 2 instead of where they belonged. The second one is I changed a null line to include a blank so that an append command would not take that as "end of input." Apparently the version of ex on my system interprets a null line the same as a "." entry.

I'm sorry for having put this of for such a long time. There are areas that are more 'Tales From The Crypt' than 'In Remembrance Of Things Past'. But it's Halloween season so I'm grabbing spikes and crucifix ... Have a look at ftp://ftp.sap.com/pub/sapdb/bin/tmp/fixgram.tgz. This contains a changed fixgram, which saves all the intermediate results of the editing session. It also contains these intermediate results as written on my machine. Maybe this hints at the problem. cd sys/src/base/ptoc/pcomp rm y.tab.c cp <whereever>/fixgram . make -f pgenc y.tab.c Daniel Dittmar -- Daniel Dittmar SAP DB, SAP Labs Berlin [EMAIL PROTECTED] http://www.sapdb.org/
