In addition to the normal flow of processing created by the underlying application, exit program tags allow the Web Option server to call external IBM i programs, written in any High-Level Language (HLL). The exit program can return a single 254-character value, which displays on the HTML in place of the tag itself. A sample exit program YEXITPGM (written in CL) is shipped with the Web Option product. If a value is to be returned from the exit program, it is the job of the programmer to ensure that this value is sent from the exit program as a program message in message id W2U0001 in message file YW2EMSG in Y2WEB.
