What is the purpose of MISSOVER option in an INFILE statement?
-
It prevents SAS from loading a new record when the end of the current record is reached
-
It enables SAS to scan the input data records until the character string that is specified in the @'character-string' expression is round
-
It enables SAS to continue to read the next input record if it does not find values in the current input file
-
It causes the data step to stop processing if an input statement reaches the end of the current record without finding values for the variables
MISSOVER prevents SAS from moving to the next input record when variables remain unassigned at the end of current record. Instead, unassigned variables get missing values. The other options describe different INFILE options: @'string' for string positioning, other options like FLOWOVER or TRUNCOVER. MISSOVER is crucial for reading fixed-width records.
The MISSOVER option on an INFILE statement tells SAS not to jump to a new input record if the current record ends before all the fields in the INPUT statement have been read; instead, remaining variables are set to missing. This prevents SAS from inadvertently reading values from the next record when the current one is shorter than expected.
