Hi, I have built a custom database system based on a flat text file (return delimited records, tab delimited fields). As the database file grows I'd like to modify the system to use a dbm file instead. I don't know where to start and I am a bit confused with MacPerl's implementation of DBM files. The Llama and Camel references mention that when calling dbmopen, Perl should create a pair of disk file (somefile.pag and somefile.dir). MacPerl only create one file. I do not understand why. This brings also two questions: 1 - Would a dbm file created by MacPerl be portable to Unix environment? 2 - How can I convert my text file database to the dbm format I have been looking for info in the excellent MacPerl List Archives but I couldn't find satisfying answers. Can somedy help me on this one? TIA. Stef ___S__t__Ž__p__h__a__n__e_____J__o__s__e___ mailto:jose.stephane@uqam.ca http://www.er.uqam.ca/nobel/m206474/
