TEXT FORMAT
Here you see an example of FORMAT(TEXTHDR). The first two lines are the headline followed by the table rows.
The first line defines the column names as specified in the subcommand CREATE.
The second line defines the maximum length of a column. However if the column name is longer than the maximum length, then the length of the column name is used.
The table row lines display the cell data padded with blanks up to the maximum column length.
NAME FIRST_NAME CITY
_______________________________________________________________
Bond James London
Smith John New York
Schulz Emma Berlin
Metzger NULL München
Wagner Frankfurt
Note that INGRDS makes a difference between "empty string" and "NULL".
An empty string is a character string with length 0, for example the FIRST_NAME of Wagner is the empty string. But the FIRST _NAME of Metzger is NULL.
