2.8 A Programming Example

The following is a program text file that illustrates the use of the F-TRAN language in building a

simple single loop controller. This text is converted to the run time program using the MicroMod

programming utilities (FPP, CPILE6, LINK) available in 53HC3300C or with 53SU5000 Rev. 3.
