Execute Form Mode

How to Use the Execute Command

Forms are printed in the Execute Form mode. In addition to printing the form in the Execute Form mode, variable data can also be entered onto the form “dynamically” during the Execute Form mode. This dynamic data input during the Execute Form mode includes page numbers, alphanumeric data fields, and bar code data fields. Pagination, described on page 78, is performed in the Execute Form mode. Dynamic alphanumeric and bar code data require additional commands within the Execute Form mode.

The fastest method for repeated forms printing is to use the form feed character. Rather than sending a series of Execute/Normal commands, which slows the process by performing an open-print-closeform sequence, the form feed character instructs the IGP to start a new page with new EVFU, dynamic and overlay data using the existing Execute commands for the form. The EVFU Data-DynamicData-OverlayData-Form Feed Character sequence can be repeated indefinitely while maintaining the optimum print speed within the original Execute command.

Note When a form count is not specified, a single line spacing (or a line containing overlay data) must always separate an EXECUTE command from a NORMAL command.

To Execute Forms Rapidly

In order to save reloading time, the IGP remembers the last form executed. However, a form must be loaded if it was not the last form executed, if it was used with a CREATE command since the last EXECUTE, or if any logo has been created.

When the form is found in memory, it is loaded and execution resumes; otherwise, the “FORM NOT FOUND” error is printed.

Print Formats in the Execute Form Mode

The Execute Form mode has two print formats. The standard execute command format, shown on the next page, is used for executing nonincremental data and incremental fixed data. An incremental execute command format, containing two additional parameters, is used for executing incremental dynamic data and is discussed on page 65.

During the Execute Form mode, the IGP responds to regular print format commands such as 8 lpi, and elongated characters. Some commands can be used in other modes in addition to the Execute Form mode. For example, Compressed Print, Expanded Print, Execute, Ignore, Select Format, and Vertical Line Spacing, which are also Normal mode commands, can be used in the Execute or Create Form modes. The IGP alternate character set can also be used in the Execute Form mode.
