ROWw.d Informat

Reads a column-binary field down a card column.

Category: Column Binary

Syntax

ROWw.d

Syntax Description

w

specifies the row where the field begins.

Range 0–12

d

specifies the length in rows of the field.

Default 1
Range 1–25

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 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.
