Allow me some comments to Gottfried Burckhardt's great article in the latest PTP. LXPLORE, which was written by me, is NOT shareware, but freeware. It can be used absolutely free and I can guarantee no support for it.
LXFF ("LX Fast Find"), which was also mentioned in this article, can find entries in very huge, sorted, comma-delimited files. It works very fast, even if the file size is many MB. I wrote it for my own use to find addresses and phone numbers in an excerpt of "D-Info", a CD containing all German phone numbers. If anybody is interested in LXFF, please let me know.
