# xxCNVT File

To determine which conversion program to start with, Resource Manager uses the xxCNVT data file for the application. The xxCNVT file stores the following data for each data file in each version:

Description | Variable Name | Len
Application ID | AP$ | 2
Version | VER$ | 5
File name | OSFIL$ | 12
Message | MSG$ | 1

To create the file, use the Create xxCNVT File function on the SD Utilities System File Maintenance menu. Enter one record for each file in each version. For company-specific files, use a lowercase x (when verifying files, the x is replaced by the company ID). For example, if the application starts at version 3.20, you need a record for each conversion step.

AP | 3.20 | APCHx
AP | 4.00 | APCHx
AP | 4.10 | APCHx
AP | 4.50 | APCHx
AP | 5.00 | APCHx
AP | 5.10 | APCHx
AP | 6.1x | APCHx
AP | 6.5x | APCHx
AP | 7.5x | APCHx
AP | 7.6x | APCHx

The xxCNVT file is merged into the OSCNVT file. OSCNVT keeps all the verification information for all applications that are installed on the system.
