Calling a VB program from 5250 emulation

[Guest.Visitor]

We would want to call a Visual Basic programm from a Client Access 5250 session, picking informations on the screen to pass them as parameter to the VB program. For example, We've a VB program that can make phone calls, if we've a customer phone number at a specific location on the screen, we'd want to take this number and to activate the VB program with this parameter. I saw something about DDE in IBM documentation but the explanations are not very clear.

Check out the RUNRMTCMD command. Use the SEARCH function of this forum to learn more about it.

RUNRMTCMD could be a solution but, if somebody have some experience using DDE on client access 5250 emulation, it could be interesting because there's no need to change the AS/400 program, all the job would be done on the PC.
