Several years ago I wrote an FB II leasing program for a client (converted from QB). Now they want some changes but I lost the source code due to a hard disk crash (I can't believe I can't find my backup!). I can rewrite the source code, but need to use the existing data files that are larger than 2 meg. Unfortunately, I do not know the format of the data files (e.g. whether they are records or numeric arrays, if characters then the variable size, etc.). Does anyone know how I can read or print the existing files to understand the data structure so the FBII rewrite can again read these files? Thanks in advance! Doug Stemen
