A snippet from the file itself follows. I've included a bit before and after the place where the error appears to occur. If you like, I will email you the file, it's rather small, but didn't want to send it with out solicitation. -8.7066605E+01 1.3024831E+01-8.7066605E+01 1.3024831E+01 999 578-8.7019020E+01 1.3023805E+01 -8.7019020E+01 1.3023805E+01-8.7019020E+01 1.3023805E+01 -1 0 0.0000000E+00 0.0000000E+00 TOL 2 1 2 2.0000001E-03 2 2 0.0000000E+00 3 2 0.0000000E+00 4 2 0.0000000E+00 5 2 0.0000000E+00 6 2 5.9793243E-02 7 2 5.9793243E-03 8 2 5.9793243E-03 9 2 5.9793243E-03 10 2 5.9793243E-03 -1 0 0 0 0 0 0 TX7 2 0 4 2 0 1 0 6 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1.2700000E+00 1.6766226E-02 0.0000000E+00 0.0000000E+00 -8.6507622E+01 1.6335363E+01 -8.6507622E+01 1.6335363E+01 Roatan 0 4 2 0 1 0 9 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0.0000000E+00 1.6408410E-02 0.0000000E+00 0.0000000E+00 -8.7678352E+01 1.5876268E+01 -8.7678352E+01 1.5876268E+01 Please let me know if you require more information.
I have seen this issue reported before, I thought it had been addressed or at least documented in a bug but I guess I forgot to do it. Anyway, the source of the problem is the blank subclass name (the blank line that follows the "TX7 2" line). The second line of a TX7 section should contain the subclass name which is used to build the filename of the .TX* files in the coverage directory. The workaround until this is fixed would be to enter some arbitrary name on the line that follows the "TX7 2" line. e.g. TX7 2 cities 0 4 2 0 1 0 6 0 1 0 0 0 0 0 0
The empty subclass names really seem to defeat the logic of the file format, or at least the implementation in avce00 used to skip empty lines, I don't remember why exactly I used to skip empty lines but there must have been a good reason. Anyway, since those empty TX7 subclass names seem to be common (possibly from a single source?), I will implement a specific case just for TX6/TX7 section that should not affect the way other other supersection types such as RPL and RXP are handled. The hack will default to using class name "TXT", resulting in a "txt.txt" file being created in the coverage directory. If the coverage is ever exported then the subclass name TXT will show up in the E00 instead of the empty subclass name. If someone can import one of those E00 files in Arc/Info and tell me how it names the .txt file then I can adjust the lib to use the same behavior.
Created an attachment (id=110) [details] Patch that fixes this for TX6/TX7 sections only
Fixed in CVS, will be part of next release. Feedback on the patch welcome.
