Pre-Recorded Scripts with Session Integrator

  • Artigo

The SessionDisplayScript class allows users to use a script created in the Host Integration Server 3270 client and play it programmatically.

The script can implement variables using a double percent sign on each end of the name, for example, %%MYVARIABLE%%. These variables are resolved using the SessionDisplayVariableCollection class provided in this class. In addition, the script file can contain environment variables using the standard notation which this class will translate.

SessionDisplayScript Class

The input script must be a normal text file with one command per line. The Script file supports the following commands:

Command Description
SETTIMEOUT {timeout},{label} Sets the default timeout for all commands and the label where processing should continue. If no default is set, 30 seconds is assumed.
WAITSESSION {wait} Waits for the session to be in the input wait state before returning. The accepted values are: SSCP; LULU; UNOWNED
WAIT {seconds} Waits the input number of seconds and then moves to the next command. The WAIT command can be replaced by the WAITSTRING command to wait for a specific string on the screen.
SETCURSOR {ROW},{COLUMN} Moves the cursor to the desired position on the screen. If the position is not found on the screen, the script is aborted and a ScriptError Exception is returned with an InnerException of the actual Exception when running the script.
SEND {string}, {%environmentvariable%}, {%%sessiondisplayvariable%%} Causes the string to be sent to the screen using the SendKeys method. Variables can be input that are matched against the SessionDisplayVariablesCollection passed into the class. If a variable is not located in the script, the script is aborted and a ScriptError Exception is returned with a InnerException of Variable {name} not located in collection.
GOTO {label} Allows for scripts to jump to labels below the current line. If the label is not found, the script will abort with a ScriptError exception and an InnerException of “Label {name} not found”. {label} = A way to define a freeform label in the script that can be used in branching scenarios.
