This command can be used to create variables in the action script. After setting a variable, the value can be accessed using the parameter inspector.

A parameter can only have one value. Trying to set an existing parameter to a different value will result in an error.

parameter "<name>"="<value>"

Note that both the name and the value of the parameter must be inside quotes.


Defines a parameter named loc that contains the pathname of the tmp folder, and uses it to write configuration information to a file.

parameter "loc" = "{pathname of folder (value of variable "tmp" of environment)}"
createfile until end
Operating system = {name of operating system}
Processor count = {number of processors}
delete "{parameter "loc"}\config.txt"
copy __createfile "{parameter "loc"}\config.txt"


The saved parameter value is always a string.

If there is any error in evaluating the relevance expression to create the parameter, then the parameter will not be set. If the relevance expression results in multiple values then, then the command fails.
