Hi,

I am in the process of updating code I've inherited as I learn IDL, and
noticed that it uses the following workflow for fixing errors in
tab-/comma-delimited files:

1. Use file_search to generate a list of files to work on

2. Use FOR loop to iterate through each file

2.1 Create a float array with the same dimensions as input file
2.2 Load the data into a string array with 'openr' -> 'strarr' ->
'readf' -> 'close'
2.3 Loop through each line doing various tests/operations
2.4 Copy the fixed data into the float array in 2.1

3. Write the float array with 'openw' -> 'printf' -> 'close'

Based on what I'm reading, it seems this should be more efficient by
using 'read_ascii' and then fixing the errors with array indexing and
then writing the data back. Is this worth pursuing, or are there any
recommendations for a module I should know about?

Thanks,
