Dear Ferret Users:
Am looking for some suggestions on how to read an ASCII file (example below) using Ferret. I would like to be able to skip the first two records and then read the third as an integer (69 in this case), skip the fourth record and then read the "integer" number of records of input with each record having 5 columns.
The reason I need to do this is sometimes, there are more a few files of the format below concatenated and the number of records of each file is specified always as below in separate blocks.
Thanks in Advance
