title: Reading from external file
body: <p>I am trying to find out the format and informat to the below.
  I have a .csv file with contain values like 10,900,900.111111 or 999.999 I use the File Reader to read this .csv file. Default File Reader type of value is 'Character' length '8' I used INPUT to convert to Numeric and TRANWRD to replace 'comma' to 'space' and received 109009 value. Which format and informat should I use to with high accuracy reflect the comma and decimal data. Currently the largest number of displayed digits in Sas table have eight digits and in my .csv file some number have as many as sixteen digits.
  Thank you,</p>
