The *FX command can be used to control some of the system's "special effects", such as keyboard repeat rates or manipulating the Escape condition.

*FX is in fact a convenient way to call OSBYTE routines from BASIC programs or the command line. For example, to set the keyboard's auto-repeat rate you set the routine number A to 12 and load the repeat rate into L, then call OSBYTE like this:


*FX takes up to three arguments, A, L and H, and passes them to OSBYTE. The above code could therefore be rewritten as follows:

*FX 12,4

All arguments are specified in decimal. The L and H arguments are optional.

For a full list of available *FX routines see the OSBYTE section.


*FX A[,L[,H]]
