INTNX function

Learn INTNX function in SAS through the exact construct, a dedicated example, a boundary case, and a mastery check.

10 min read • Intermediate

INTNX function is an atomic SAS lesson inside Functions. The example uses the specific syntax, command, API, instruction, or language rule named by this lesson.

Study the construct itself, then change one relevant input and predict the result before running it. That keeps this lesson focused on INTNX function rather than on generic SAS syntax.

Topic-specific example

sas-03-08.sas
sas Try It Live
data _null_; next_month=intnx("month",today(),1,"same"); format next_month date9.; put next_month=; run;
Edge case / engineering note

For INTNX function, inspect the SAS log as well as the output data set; type conversion, missing values, and BY-group ordering can change results without stopping execution.
