use of the SUBSTR function to match to a core part of an occupation or industry word; use of SAS MERGE to get information from several existing databases and thus enlarge the extant coding database; use of SAS MERGE for quality control of coding and use of the INDEX function for examining...
Text strings supplied as parameters for a function must always be wrapped in quotes, regardless of whether they appear in the Recognition field or the Value field. The CONCAT() function should be used to return a text string containing special characters such as ampersands that could be interpre...
I am writing a macro to send e-mails, using a rest api available in our company. (The macro will be deployed as a sasautos macro.) The attachments parameter should allow to pass a list of file paths, so this should be valid code; %send_mail(subject=Voorbeeld...
