Delimiter sensitive Data(DSD an infile option)

The DSD option: The DSD (Delimiter-Sensitive Data) option for the INFILE statement

does three things for you. First, it ignores delimiters in data values enclosed in quotation marks.

Second, it does not read quotation marks as part of the data value. Third, it treats two delimiters

in a row as a missing value. The DSD option assumes that the delimiter is a comma. If your

delimiter is not a comma then you can use the DLM= option with the DSD option to specify the

delimiter. For example, to read a tab-delimited ASCII file with missing values indicated by two

consecutive tab characters use

INFILE ’file-specification’ DLM=’09’X DSD;
