Displaying data files on your PC

As soon as you have transferred data files from the Workabout to your PC (or have created them on a portable PC) you will want to analyse and print them for your records.

The .PRN file

The .PRN file format contains ASCII characters which can be read by a wide range of text reading programs, and by some spreadsheets. An example printout is shown below.

The .CSV file

The Comma Separated Value format is a common format where ASCII characters are separated into fields by commas, and text is identified by being enclosed in "...". This greatly simplifies importing the files into spreadsheets for further analysis and printout. The example below was created in Microsoft Excel 5.0
