Hi,

I have a SAS dataset as follows:

data source;

input id cols $10.;

cards;

1 gender,age

2 address

;

run;

Now, I would like to transpose those values in COLS column which is currently separated by a comma. The target dataset is as follows:

data target;

input id cols $;

cards;

1 gender

1 age

2 address

;

run;

How will I be able to achieve the target dataset?

Interesting. From the SAS documentation for the subsetting if:

If the expression is false (its value is 0 or missing), no further statements are processed for that observation or record, the current observation is not written to the data set, and the remaining program statements in the DATA step are not executed. SAS immediately returns to the beginning of the DATA step because the subsetting IF statement does not require additional statements to stop processing observations.

(emphasis by me)

This would imply that a value for cols of "Age,,Gender" would lead to "Gender" being dropped, but that does actually not happen. SAS only exits the do loop.

Learning never stops.
