Creating SAS dataset with variable containing text string values

RobertWF2 — Tue, 17 Jan 2023 17:10:29 GMT

I'm trying to run the following code that creates a data table with a text string for the Dimension variable, however the variable values in the bal_cat dataset are all blank.

data bal_cat;
infile datalines delimiter='     '  truncover dsd;
length order 8.0 var_name $ 50;
length Dimension $ 200 ;
input order     var_name :$     Dimension :$ ;
datalines;
1    agegrp1    "Age Group: <= 74"
2    agegrp2    "Age Group: 75-79"
3    agegrp3    "Age Group: 80-84"
4    agegrp4    "Age Group: 85-89"
5    agegrp5    "Age Group: 90+"
6    gender_f1  "Female"
;
run;

If you want to have embedded spaces (actually embedded delimiters) then you have three options.

1) Use fixed length fields.

2) Use the & modifier. That will require two delimiters to mark the start of the next field.

3) Use DSD option. That will allow you use quotes the protected delimiters in the value. But you cannot have more than one delimiter between the fields.

4) Use the DLMSTR= option on the INFILE statement to specify a multiple byte delimiter string.

NOTE: Do not embed TAB characters in data (or programs for that matter) and definitely not in quoted string. They are too easily misunderstood by programmers and the programs you use to edit the file. In code you can use the hex literal '09'x to specify a TAB character.

PS There is no need to include decimal places when specifying a LENGTH. SAS can only store variables using whole numbers of bytes so you only need integer values.

Thanks Tom! That solved it!
