* FW 0 is reserved for the logical program counter
FW 2 to FW 198 (F 2.0 to F 199.7) permissible for the user porgram
FW 200 to FW 254 (F 200.0 to F 255.7) are only permissible in blocks as scratch flags. Scratch flags must be defined, set or reset at the
start of block execution as well as after conditional and unconditional block calls. This prevents data exchange with other blocks.
