Translation Table Clause Samples

Translation Table. ‌ The translation table in the Software Wedge allows you to translate characters received from your serial device just before data is transferred to another application program - after the data has been parsed and filtered. If you select the "Translation Table" option from the Define menu, the translation table will appear as below: If the Software Wedge is in "Send Keystrokes Mode", then the translation table is used to convert individual characters to specific keystrokes. Data transmitted via an RS232 serial connection consists of ASCII characters. Because many ASCII characters do not correspond to a specific keystroke, the Translation Table provides a way to map characters to specific keystrokes. To translate characters, simply select the character that you need to translate with your mouse and then click the "Translate" button. This will display the following "Keystroke Selection" dialog box that allows you to select a specific keystroke or key combination. The keystroke selection dialog box contains a list of all keystrokes as well as three check boxes that allow you to indicate the toggle key states to be used in conjunction with the selected keystroke. The first three choices in the keystroke list (Ignore, Void Record & Null) do not represent actual keystrokes but instead have special meanings when selected. Translating a character to Ignore causes the character to be ignored altogether by the Wedge. When a character translated to "Ignore" is received, it will be discarded thus it will not appear anywhere in the input data. Also, because the character is being ignored, its presence is not counted when reading data into a fixed length data record or a fixed length data field. Thus, Ignore effectively removes the character from the input data stream before it is even read in by the Wedge. If you translate a character to Void Record, it causes the Wedge to invalidate and remove the entire current record. If a character translated to "Void Record" is present anywhere in an input data record, the entire record is completely ignored and will not be transferred to your application program. For example, suppose you had a device that always transmitted a header record before each set of data records and you want to get rid of the unwanted header record. If there was a specific character that always appeared in the header record but never appears in any of the data records, you could remove the header record by translating the one specific character to “Void ...
