Symptom

 When transferring a command script task list over from earlier versions to Integration builder, the integration errors out, claiming that /X is not a recognized command.

Environment

 BarTender 2016 and later Integrations

Fix/Answer

 The /X command is a command line parameter that will close a BarTender document without saving it. This parameter worked normally in Task Lists and works with direct commands to BarTender but it errors out when using the Integration Builder.

To fix this issue, replace the /X command with /CLOSE. Here's the description of the command from the help file:

/CLOSE

Closes all open BarTender documents without saving. To close the active document only, use /CLOSE with /AF. To save the open documents prior to closing, use the /S command with /CLOSE.
