Example Script 2: Multicolumn Record Reports
Output Records
Mailing label files such as this simple 2-up (2 columns of mailing addresses) example are a special case of the fixed format style. The input source file in this example contains the text for three-line address labels, two across the page. Some text is missing if a label is obsolete.
Note: A far more versatile mailing label script is provided in the CXL superpack. This is simply an example script that illustrates some of the basic CXL principles behind that script.
The script reads in three lines from the input file for every two output address records. Empty lines are rejected if they are not part of obsolete labels. Label information is extracted from specific locations in the input line, from two labels per line, and stored in an array. Once all three lines are read, CATCHUP mode is used to accept the accumulated information.
The values of the variables listed in the accept statement will be displayed in the Source Data Browser in the Map Designer and written to a data file or table through the Map Designer.
