A format defines how data will appear.
|
|
The format command defines a format.
|
|
The basic syntax follows:
|
|
|
|
format NAME = formatdata
|
|
|
|
The format definition ends with a single period on its own on a line.
|
|
The format data come in pairs of lines.
|
|
In each pair, the first line, called the picture line, lists how the data will look;
|
|
the second line, called the argument line, lists the global Perl variables that will hold the data.
|
|
When the report is generated, the data values get plugged into the picture lines.
|
|
|
|
For example,
|
|
|
|
format NAMES=
|
|
Last name : @<<<<<<<<<<<<<<<<<<<<
|
|
$lastname
|
|
First name: @<<<<<<<<<<<
|
|
$firstname
|
|
|
|
.
|
|
|
|
|
|
The @<<<<<<<<<<< format defines a left-justified data field.
|
|
The number of < characters defines how many spaces are allotted for the field. The lines with variables, $lastname and $firstname, aren't printed.
|
|
Only the lines that define the format are printed.
