1. A method, the method comprising: in a hardware processor, graphically building a COBOL application processing vector in a graphical user interface of a transactional workflow driver (TWD) by: presenting in the graphical user interface a visual representation of user selectable elements for building the COBOL application processing vector, wherein the selectable elements comprise one or more independent COBOL processing components; receiving a user's selections from the selectable elements; presenting in the graphical user interface a graphical representation of an application flow that is determined based on the user's selections from the selectable elements including one or more of the independent COBOL processing components; translating the graphical representation of the application flow into a computer readable format representing the COBOL application processing vector comprising the user selected one or more of the independent COBOL processing components; generating and storing, in a memory coupled to the hardware processor, the COBOL application processing vector, wherein the COBOL application processing vector identifies a sequence for processing the user selected one or more of the independent COBOL processing components; and deploying the COBOL application processing vector using the TWD, utilizing one or more service request message application program interfaces (APIs) for one or more transaction servers or transaction managers; managing interactions with the COBOL application processing vector using the one or more service request message APIs to satisfy service request messages responsive to the interactions; receiving, using the TWD, a user interaction for the COBOL application processing vector through the one or more service request message APIs; translating, using the TWD, the user interaction into a COBOL application processing vector service request message for the COBOL application processing vector; identifying, using the TWD, which of the independent COBOL processing components with which to communicate the COBOL application processing vector service request message; communicating, using the TWD, the COBOL application processing vector service request message to an identified independent COBOL processing component; executing, using the processor, the identified independent COBOL processing component responsive to the COBOL application processing vector service request message; receiving, using the TWD, a return code from the identified independent COBOL processing component; determining, using the TWD, whether the return code includes: a result; or a subsequent processing component reference to another independent COBOL processing component; and in instances when the return code includes a result, communicating, using the TWD, the return code in a service request response message through the one or more service request message APIs to a user.
