[Tutor] Missing Data in Txt Files

[Benson, Randall]

Hello,

Does anyone have a program that will read txt file data and insert -9999
or similar for missing data?  I have 10minute data and there are hour
chunks that are missing that need a missing data insert for that missing
hour but not the 10min period.  The txt file has a date column (yymmdd),
a time (hhmm) column and the rest are data columns shown below.  See
column 1 below with i

080618 1000  4.62  7.00 227.0  -3.38  -3.15   0.00 9999.99 9999.99  0.91
080618 1410  5.19  7.30 232.0  -4.09  -3.20   0.00 9999.99 9999.99  1.03
 
Muchas gracias,
