Importing tab delimited files

[pronabesh]

Hi SAS Community,

I am trying to import a tab delimited file (sample file attached) where the first line is the variable names and lines 2 and 3 contain data from one id (should align as a single row in the SAS file). I used the following Import syntax:

proc import  out=temp datafile='C:\Users\template.txt' dbms=dlm replace;

  delimiter='09'x;

  guessingrows=32767;

  getnames=yes;

run;

The imported file is not in proper format and the variable names don't align with the variable values. I suspect this has to do with special characters in the character variables but for the life of me, I cant figure out how to fix it.

Any help will be much appreciated!

Best,

Pronabesh

SAS cannot guess correctly that two rows of data are a single record, it will align first column, second etc. according to the delimiter provided. I don't see any special characters, which are you concerned with.

You may need to investigate the details of the input statement regarding reading multiple lines and such.

You didn't provide much in the way of data to do any testing and you will want to specify what the expected result is for example data.

Thanks ballardw,

The SQL data miners provided me this data as tab delimited. I am assuming that every variable should be delimited by tab. However if I run my syntax on the sample dataset (agreed this is only a small sample) the delimiting does not work. I used '09'x as the delimiter.

Did you create Template.txt with an editor?  I see '0d0d0a'x follow by " double quote on the next line.

I'm thinking that '0d0a' was created when you saved it.

Can you show a bit of the original unaltered file.

Hello Data_Null,

Thanks for your response. Here is a bigger cut of the data (see attached). I can send you the unadulterated file too but will need to strip some columns.

[data_null__]

Run this program on the original file.  Find the place with the '0d'x and show the output.  I want to see what follows the '0d'x in the original unaltered file.

filename FT55F001 'path-to-original-file.txt' lrecl=100 recfm=F;
data _null_;
   infile FT55F001;
   input;
   list;
   if _n_ gt 20 then stop;
   run;

This is what I see now but I think that gets "created" when you modify the file so you can post it.

The issue was carriage return and linefeed characters within quoted strings.
