... If you have a program to convert data to MIDAS input format, fine. ... All you need to do is cannibalize the part of the existing program that reads the data, and add a short piece of code to re-format the data first as a flat ASCII file, one measurement per line; and then convert this to *.tbl format. ... It's just like the process of creating a program-star table. ... You may decide to write a short MIDAS script to apply your format-conversion program and the edited *.fmt file to each night's data...
