10.10 Solving Report Problems

Several variations to the basic report format are discussed in the next sections.

10.10.1 Printing More Than One Logical Line on a Single Physical Line

When your report has only a few columns, you can print several logical lines on one physical line. If you were to print names and addresses on four-up self-sticking multilabel forms, you would print the form left to right and top to bottom, as shown in Figure 10-20 and Example 10-11. To print four-up self-sticking labels, you must format each logical line with four input records.

However, if the columns must be sorted by column, the task becomes more difficult. The last line at the end of the first column is continued at the top of the second column of the same page, indented to the right, and so forth, as shown in Figure 10-21 and Example 10-12. Example 10-12 defines a table containing all data to appear on the page. It reads the input records, stores the data in the table as it is to appear on the page, prints the contents of the table and then fills spaces. When it reaches the end of file, the remaining entries in the table are automatically blank. You can extend this technique to print any number of logical lines on a single physical line.

10.10.2 Group Indicating

The group indicating process greatly improves a report's readability where long sequences of entries have some element in common. You print the element once, then leave it blank for subsequent lines, as long as there is no change in that element. For example, if your sample file's sort sequence is State (major key) and City (minor key), you get sequences like those in Table 10-2.
