Would just like to point out that the 5.14 script manual (here: https://s3-eu-west-1.amazonaws.com/ur-support-site/208316/scriptManual_SW5.14.pdf) does not detail the ability to set the runstate of the GP_Integer/float registers. It only shows this for the GP_boolean registers.
You can use the Installation node in Polyscope to assign a value to an int register and then view the script for that program which shows that these ARE commands, they just aren’t detailed in the manual.
Example: “set_runstate_gp_integer_output_to_value(47,1)” is an undocumented command.
