Generating File Handling Code

When you create a data set in the Data Set Designer, you determine what sort of file handling code AcuBench will generate in a given program. As you work with your program, you can change what code will be generated in the Data Set Member Files dialog box. The Data Set Member Files dialog box lists all of the data sets defined for a program, as well as information about the file handling code currently specified for each data set.

To open this dialog, go to the workspace Structure view, open the desired Program node, right-click the Data Set node, and select the Referenced FD/SL Files command.

To change the OPEN code generated for the file, do any of the following:

• In the Open Option portion of the dialog, mark the check box next to the data file name in the Open column to have AcuBench generate OPEN code for the file. If this check box is marked, an Acu-Open-file paragraph is generated, by default, into the .prd COPY file. Remove the check mark to stop generating this code paragraph. If the box is not marked, changing other open option details for the data set has no effect.
• the Exclusive column, mark the check box to indicate that a file can only be opened by one program at a time.
• In the Mode column, select an open mode (INPUT, OUTPUT, EXTEND, I/O). The default mode is I/O.
• In the Locking column, select a lock mode from the drop-down list. The default locking mode is None.

To change the I/O handling code generated for a file, do the following:

• In the IO Option portion of the dialog, click a file’s I/O Operation field, then expand the drop-down list.

  The list shows all of the file operations that can be performed on the file, based on the open mode selected in the top portion of the screen.

  Note that this list is populated based on the file handling operations defined in the file’s DLT. This means that if you selected the Do not generate any IO Paragraphs radio button on the I/O Handling tab of the File Designer, nothing will appear in the I/O Operation field.

• Mark the check box next to an I/O function to have AcuBench generates a paragraph to perform the selected function. Remove the check mark to cause AcuBench to stop generating code for performing the selected operation.
