VCL RUNTIME RATES
VCL is an interpreted language. Each line of VCL code is converted by the
WinVCL compiler into an array of pseudo-code which can then be flash loaded
into the controller. The controller interprets these pseudo-codes one line at a
time while the system is running (powered). The table below lists the service
rate at which the VCL interpreter runs each of the various functions, and also
lists how many instances of each function are available to the VCL software.
