Currently have an application that calls a third party C program for access to customer info on a mainframe. This process will be replaced by something called TN3270 Gateway Transaction access, which I believe involves accessing an HTTP:// address, passing information to it for a query and receiving information back into the COBOL program. Have not done this before but review of the doc seems to point to either and EXEC or EHTML instruction. Has anybody successfully done this before? Would appreciate any examples. Thanks. I'm using NetExpress3.1, SP1 with all current patches, our app sits on an NT 4.0 server.
