PIPE VET Streams 262 Programming: Pipes application running on the VOST returns a message and a full screen, both the message and full-screen data are returned to VET. When VET is used as a command or as a subsequent stage, VET writes data to the virtual screen belonging to the VOST. Data is written in the form of simple text where one line is written for each input-capable field on the VOST. Stream Type Number Supported Input 1 Output 2 Termination Conditions If specified as a first stage, VET terminates when the output stream is disconnected or when it finishes processing its output. If specified as a subsequent stage, VET terminates when the input stream or the output stream is disconnected. Operand Descriptions action key Specifies the action key to be sent with the data. Any of the following keys are valid: PF1 PF2 PF3 PF4 PF5 PF6 PF7 PF8 PF9 PF10 PF11 PF12 PF13 PF14 PF15 PF16 PF17 PF18 PF19 PF20 PF21 PF22 PF23 PF24 PA1 PA2 PA3 ENTER CLEAR NOKEY After the data specified in the input stream and /string/ are written to the virtual screen, the action key is passed to the application running on the VOST. The application responds as if the /string/ data was entered and the designated action key on a terminal was pressed. Unless another action key is specified, the default ENTER is sent to the application with the data. NOKEY is a special action key. NOKEY indicates that the data specified in /string/ is to be written to the virtual screen, but an action key is not to be pressed. This is as though a user enters data on a panel and does not press Enter, a PF, or PA key. CURRENT Specifies that the virtual screen image on the VOST at the time of the call is to be returned to the stage. CORRWAIT is not required with VET CURRENT. Any pending I/O requests sent by the application running on the VOST are applied to the virtual screen before returning the screen image to the stage. Note: The entire screen image is returned to the stage in message BNH150I. FIELDS Specifies that one line for each field on the virtual screen follows the BNH150I message header.
PIPE VET Note: For any field of data that has an intensity attribute of DARK (ID), the entire returned field information has presentation attribute of DARK. As a result, the data cannot be displayed. One way to see the data is to use a COLOR NORMAL stage subsequent to the VET stage. NAME Specifies the name of the VOST. NAME must correspond to the NAME on the ATTACH command that created the VOST or attach name. VET NAME indicates that the VET stage is to interact with the named VOST. If a VOST was created by the ATTACH command without a NAME, the VOST is dependent on the invoking procedure. In the case of a dependent ATTACH, if you code VET without specifying a NAME, VET interacts with only one VOST: the VOST created by the ATTACH command within the same procedure as the VET stage. NAME must be specified if VET is to interact with an independent VOST, that is, a VOST created outside of the procedure family. NAME must be specified if VET is to interact with an independent VOST, that is, a VOST created outside of the procedure family. NEXT Specifies that the next update to the virtual screen is to be returned to the stage. This update can either be currently pending or can be received at a future point in time when the application next updates the virtual screen. Specify CORRWAIT as the next stage after VET NEXT. CORRWAIT automatically ends when: v The application running on the VOST is ready for input. v The application terminates. For additional information on CORRWAIT, see “PIPE CORRWAIT ” on page 54. In general, VET NEXT does not return a complete screen image. Only the parts of the virtual screen sent by the application as the screen updates are returned. Depending on the application, all or part of the virtual screen can be updated. ROWS Specifies that the data displayed on the virtual screen is to be returned to the stage as a series of 24 lines of 80 characters each following the BNH150I message header. Positions on the virtual screen occupied by start field orders are blank (X'40'). When using VET NEXT ROWS, those screen positions not updated by the application running on the VOST contain X'FF' characters. Note: For any row of data that contains any field with an attribute of DARK, the returned row has a presentation attribute of DARK. As a result, the data is not displayed. One way to see the data is to use a COLOR NORMAL stage subsequent to the VET stage. For additional information about start field orders, refer to the 3270 Information Display System library. ROW.COL Specifies the starting row and column on the virtual screen where the data specified by the input stream or /string/ is to be written. If ROW is specified without COL, the default value of 1 is used for COL. If ROW.COL is not specified, VET writes the data specified in the input stream /string/ beginning at the current cursor position on the VOST virtual screen. If the current cursor position is in a protected field, VET simulates a tab to the next unprotected field and writes the data beginning in that unprotected field. Chapter 2.
