By default, when you run MFDAS from the command line it uses the server, node, and port most recently specified by the Drag and Drop interface. However, you can specify different settings to be used by the MFDAS command line by setting the MFA_SERVER_PARMS environment variable before running mfdas.exe. The format of this environment variable is as follows:
SET MFA_SERVER_PARMS=MFSRV:name,MFNODE:node,MFPORT:portnum
where:
SET MFA_SERVER_PARMS=MFSRV:MVSSRV,MFNODE:MVS.SERVER.COM,MFPORT:6000
