What are Infile options in SAS?

INFILE/FILE statements have extensive options to help provide that information and allow SAS to process a rich and varied range of files with minimal effort. INFILE/FILE also work with other SAS statements such as FILENAME, DATALINES, PUT and INPUT to provide extensive data input and output in the DATA step.

What is SAS Missover?

The MISSOVER tells SAS that when you try to read past the end of the line just return a missing value. The default behavior is the FLOWOVER option in which case SAS will move on to the next line to look for enough values to satisfy the input statement.

What is the use of DSD?

DSD stands for Delimiter-Sensitive Data. The DSD (Delimiter-Sensitive Data) in infile statement does three things for you. 1: it ignores delimiters in data values enclosed in quotation marks; 2: it ignores quotation marks as part of your data; 3: it treats two consecutive delimiters in a row as missing value.

How do I use DLM in SAS?

The dlm= option can be used to specify the delimiter that separates the variables in your raw data file. For example, dlm=’,’indicates a comma is the delimiter (e.g., a comma separated file, . csv file). Or, dlm=’09’x indicates that tabs are used to separate your variables (e.g., a tab separated file).

What are some common options for the infile statement in SAS?

For example, if your file contained the line 20,30,,50 SAS will treat this as 20 30 50 but with the dsd option SAS will treat it as 20 30 . 50 , which is probably what you intended. Second, it allows you to include the delimiter within quoted strings.

What does DSD stand for in infile statement?

The DSD (Delimiter-Sensitive Data) in infile statement does three things for you. 1: it ignores delimiters in data values enclosed in quotation marks; 2: it ignores quotation marks as part of your data; 3: it treats two consecutive delimiters in a row as missing value.

How are DSD and missover related in SAS?

They are not really related at all. The DSD option controls how SAS treats (or when used on FILE statement creates) multiple adjacent delimiters. The MISSOVER option controls what happens when you try to read past the end of the current line of text.

How does DSD change the default delimiter in SAS?

The DSD option changes how SAS treats delimiters when you use LIST input and sets the default delimiter to a comma. When you specify DSD, SAS treats two consecutive delimiters as a missing value and removes quotation marks from character values. Use the DELIMITER= or DLMSTR= option to change the delimiter.
