Create a file interpreter tool to read the file.
log creates a typescript within the tool; fork causes execution of the script without a tool.
Use renderTool if non-NIL, otherwise creates an invisible one.
! Error.

See the graphics 3d documentation for a list of valid operations and their arguments.

A convenience routine for operations with real arguments.

A convenience routine for operations with int arguments.
