This is done simply by typing the variable name (or comma-separated list of names) in the OutParams property of the source shape:

Step 2. Instruct the target shape to receive this new variable as input.

Step 3. In the source shape, make the variable visible to the whole workflow.

titleIn case of streaming translator (click to expand):

Drop the Code shape from left panel in ADVANCED group and set value of the Code shape as 

Code Block
:varTaskParams: := :varTaskParams: + 'variableA;' + :variableA: + '!'

If you need to share more variables you can add them to the Code shape using syntax variable_name;variable_value!. For example, if we have another variable count to share, the Code shape value is set like this:

Code Block
:varTaskParams: := :varTaskParams: + 'variableA;' + :variableA: + '!' + 'count;' + :count: + '!'


Your final picture should look like this

Step C: Drop the Code shape from left panel in group ADVANCED after the variable box and set value of the Code shape as

Code Block

Step E: Drop another Code shape and set its value as:


Info

If you need to share more variables you can add them to the Code shape using variable_name;variable_value! syntax. For example, if we have another variable count to share, then the Code shape value will be as follows

Code Block
languagetext
IF (find(:varTaskParams:, 'variableA;') = -1) then :varTaskParams: := :varTaskParams: + 'variableA;' + :variableA: + '!';



Step F: Drop the second Call Include shape and type or select  file ../eagle_ml-2-0_cm/upd_w_state.inc

after all these additions you should have something similar to this:

To verify that new variables are passed to the target shape, run your workflow and check the Control Message tab in the Monitoring Tool.

You should be able to see your new variables as input parameters in the RTR:
