File Update Utility |
The File Update Utility is used to view, modify and update the records within a selected data file, one record at a time. You can also view other details such as file type, record size, current number of records and field information.
The Search button invokes a concurrent Search window (see File View Utility) for defining filter criteria to search the records in a Keyed data file.
(The Search button was added in PxPlus 2023 Update 1.)
To invoke this utility, use one of the following methods:
|

From the PxPlus IDE Main Launcher |

|
From the PxPlus Command line |
Enter fm and then specify the file to update using the displayed browse window. |
The File Update Utility displays the details for the selected file. A grid displays the field names, field lengths, and old/new data values for each record. Use the browse buttons to scroll through the records in the file.
The data for a field can be modified by entering the new value in the New Value column. After saving/updating the file, the Old Value and New Value columns reflect the saved changes the next time you select this file.
This window consists of the following:
