Details

Column-binary data storage compresses data so that more than 80 items of data can be stored on a single “virtual” punch card.

The ROWw.d informat assigns the relative position of the punch in the field to a numeric variable.

If the field that you specify has more than one punch, then ROWw.d assigns the variable a missing value and sets the automatic variable _ERROR_ to 1. If the field has no punches, then ROWw.d assigns the variable a missing value.

ROWw.d can read fields across columns, continuing with row 12 of the new column and going down through the rest of the rows. After ROWw.d reads a field, the pointer moves to the next row.

Example

input x row5.3 
input x row7.1 
input x row5.2 
input x row3.5

1The data line is a hexadecimal representation of the column binary. The “virtual” punch card column for the example data has row 7 punched. The binary representation is 0000 0000 0000 0100.
