TPK, VPK Call Functions

Call functions are functions which could be called up by TPK or VPK.

Call Functions - Operations

Function Descriptions
VP:= VP XOR Value 
Predefine  VP variable XOR with a constant stay in Value, and store the result back into  the VP variable
E.g. VP_N32(0x020000)=0x0055, properties'  Value=  0x00AA; result VP_N32 (0x020000)=0x00FF
BUFF:= VP 
Copy  the VP variable content to the BUFF(string format) location.
E.g. VP_N32(0x020000)=123;  result VP_STR(BUFF)=“123”  (note: number converted to string)
VP:= BUFF 
Copy  the BUFF  content to a VP variable (integer or a string)
E.g. VP(BUFF)=“123”, result  VP_N32(0x020000)=123 (note: string converted to interger)
VP:= Value 
Copy  a constant stay in Value to a VP variable
E.g. properties' Value= 123;  result VP_N32(0x020000)=123
VP:= VP + Value 
Predefine  VP variable add with a constant stay in Value, and  store the result back into the VP variable
E.g. VP_N32(0x020000)=666, Value=2; result VP_N32 (0x020000)=668
VP:= VP - Value 
Predefine  VP variable minus by a constant stay in Value, and  store the result back into the VP variable
