SAS cannot process TAB delimeter

happy_sas_kitty — Mon, 03 Aug 2020 06:58:07 GMT

Hello all,

I used the exact code here in https://documentation.sas.com/?docsetId=proc&docsetTarget=n1w1xy48wd290bn1mqalitn7wy13.htm&docsetVersion=9.4&locale=en

My sas somehow cannot separate the txt file columns by tab.

My log is pasted below:

I changed text color for line 87-89.

It seems that SAS knows that I'm using delimeter by tab.

It just fails to separate columns by '09'x

I'm using SAS Studio the web client with virtualbox win10

1) Have you run the proc export? You can ignore the note about the parameter catalog, as sas will overcome it. There is no log information expected of running the proc import.

2) Are you sure that the delimiter is '09'x and not '_' .

Why have you coded lines:

informat Name_____Gender___Age $20. ;
 format Name_____Gender___Age $20. ;
     input
              Name_____Gender___Age  $
         ;

instead, just:

    input   Name $  Gender $  Age  $ ;

If your source data is not sensitive the copy a few lines from the file and paste into a code box opened with the </> icon.

If you "value" looks like

"some name female 23"

all within a single set of quotes then the DSD option will not separate values

Since the generated variable name, instead of a more typical 3, then that makes a quote related issue possible.

Do you get just part of the name or do all three values appear in the variable?

Name_____Gender___Age

is a column name 'computed' by the External File Interface sub system invoked by Proc IMPORT when DBMS=DLM option is specified.

Because the expected tab delimiter was properly specified as

delimiter='09'x;

The underscores underscore the fact that the data file very likely has spaces instead of tabs. By default, non SAS-name characters in the header row are replaced with underscore character (_). The spaces, not being a name character nor a delimiter are converted to underscore (_)

The underscores in the EFI computed column

Name_____Gender___Age
12345678901234567890123

indicates what I surmise as @happy_sas_kitty using a text editor configured with a tab stop setting of 3, and the editor replacing tabs with spaces upon File/Save.
