MS-DOS-based Clients

With Microsoft® MS-DOS®, only one Net-Library TSR can be loaded, so there is no .ini configuration. Instead, MS-DOS environment variables are used to specify any network-specific connection information. Environment variables have the following format:

logical_name = network_specific_ parameters

Before loading the Net-Library TSR, the environment variables containing connection information must be set. If the servername parameter passed from dbopen corresponds to a currently set environment variable, the Net-Library uses the information in the environment string to determine server location and network-specific information parameters, if present. If no environment variable matches the servername passed from dbopen, the Net-Library uses the servername parameter passed from dbopen.
