Full-Screen Automation 322 Programming: Pipes When using VET on subsequent stages, you can specify the data to be written to the virtual screen, the cursor position where the data is written, and the action key to be pressed after the data is written to the virtual screen. For example, ATTACH NPDA creates a VOST running NPDA. The first panel presented on the virtual screen is NPDA-01A. To request the total events panel (NPDA-40A): NETVIEW VET /2/ In this example, a row.col was not specified, so the string /2/ is written to the VOST in the first unprotected field on the panel at, or after, the current cursor position. Because NPDA-01A only has one unprotected field, which is the command line, 2 is written to the unprotected field. The VET action key defaults to ENTER. After 2 is written to the command line, information is passed to NPDA indicating that the Enter key was executed on the VOST. NPDA responds to the VOST as though a human operator entered 2, which is a NPDA subcommand or selection choice, and pressed the Enter key. Notes: 1. You can use ENTER, PF, PA, and CLEAR keys as action keys. ENTER is the default. 2. Using NOKEY as an action key enables you to enter data on the virtual screen, but indicates that no action is to be taken. This is the same as when a human operator types data on a panel and does not press an action key, such as Enter, to indicate to the application that the input is complete. 3. If the application running on the VOST enables dynamic remapping of PF and PA keys using the NCCF SET command, the PF and PA key action keys cannot be used on the VET command. Instead, use the command to be executed in the /string/ with an Enter action key. For example, if the application running on the VOST can have PF keys remapped and as a default has PF3 set to END, code VET /END/ ENTER. Using Delimiters Delimited strings can be used when VET is a command. Strings to be written to the virtual screen must be enclosed in delimiters. The first nonblank character encountered after the stage name or row.col is the delimiter, which establishes the boundary of the text string used by VET. The delimited string ends when the same character is encountered a second time. If you want to execute an action key on the VOST without entering data on the virtual screen, specify either a null string with two delimiters with no space between them or omit the /string/ altogether. For example, if you want to press PF8 without entering data on a panel, code either of the following statements: NETVIEW VET // PF8 VET PF8 Writing in Protected Fields After a string is written to a panel on the virtual screen, the cursor is moved to the next field on the panel. If you attempt to write a string to a protected field, the cursor moves to the next unprotected field before writing the data. If there are no more unprotected fields, the cursor wraps back to the top of the panel and finds the first unprotected field and writes the data. Strings are truncated if they are longer than the unprotected field in which they are written.
Note: If you attempt to write a /string/ to a panel that does not have unprotected fields, the /string/ is ignored, but the action key is processed. DSRBS is an application that presents panels that do not have unprotected fields. For example, STATMON running on a VOST displays: STATMON.DSS DOMAIN STATUS SUMMARY (REFRESH=ON) 10:50 A HOST: HOST126 *1* *2* *3* *4* ACTIVE PENDING INACT MONIT NEVACT OTHER .....1 NCP/CA/LAN/PK .....1 ...... ...... ...... ...... ...... .....1 LINES .....1 ...... ...... ...... ...... ...... .....1 PUS/CLUSTERS .....1 ...... ...... ...... ...... ...... .....1 LOCAL MAJ NDS .....1 ...... ...... ...... ...... ...... .....5 LUS/TERMS .....5 ...... ...... ...... ...... ...... .....1 APPL MAJ NDS .....1 ...... ...... ...... ...... ...... ....49 APPLICATIONS .....8 ...... ...... ...... .....1 ....40 .....1 CDRM MAJ NDS .....1 ...... ...... ...... ...... ...... ...151 CDRMS .....2 ...... ...... ...... ...149 ...... .....1 CDRSC MAJ NDS .....1 ...... ...... ...... ...... ...... ...603 CDRSCS ...302 ...... ...... ...... ...301 ...... ------ ------------- ------ ------ ------ ------ ------ ------ ...815 TOTAL NODES ...324 ...... ...... ...... ...451 ....40 CMD==> TO SEE YOUR KEY SETTINGS, ENTER ’DISPFK’ On this panel, there are 89 unprotected fields. The fields include the command line and each of the following fields, delimited with vertical bars (|). |*1*| |*2*| |*3*| |*4*| |....1 NCP/CA/LAN/PK| |....1| |.....| |.....| |.....| |.....| |.....| |....1 LINES | |....1| |.....| |.....| |.....| |.....| |.....| |....1 PUS/CLUSTERS| |....1| |.....| |.....| |.....| |.....| |.....| |....1 LOCAL MAJ NDS| |....1| |.....| |.....| |.....| |.....| |.....| |....5 LUS/TERMS | |....5| |.....| |.....| |.....| |.....| |.....| |....1 APPL MAJ NDS | |....1| |.....| |.....| |.....| |.....| |.....| |..49 APPLICATIONS | |....8| |.....| |.....| |.....| |....1| |...40| |....1 CDRM MAJ NDS | |....1| |.....| |.....| |.....| |.....| |.....| |..151 CDRMS | |....2| |.....| |.....| |.....| |..149| |.....| |....1 CDRSC MAJ NDS| |....1| |.....| |.....| |.....| |.....| |.....| |..603 CDRSCS | |..302| |.....| |.....| |.....| |..301| |.....| |..815 TOTAL NODES | |..324| |.....| |.....| |.....| |..451| |...40| The following REXX program written to interact with this panel requests a STATMON detail panel on NCP/CA/LAN/PK. An end user places a nonblank character in the first field of the NCP/CA/LAN/PK line on summary panel. To do so in a full-screen automation REXX program, code: NETVIEW VET 4.2 /X/ This command positions the cursor at the 4th row and 2nd column, places an X in that column, and presses the Enter key. You can also code the following lines in your REXX program: input. = ’ input.5 = ’X’ input.0 = 5 PIPE (NAME REQNCP) | STEM input. | VET 1.1 Full-Screen Automation Chapter 5.
