<p>PURPOSE:To make a variable table unnecessary by using a variable number as a memory address to access a memory directly and reading out directly a numerical value or substituting the numerical value into the variable directly. CONSTITUTION:If a variable is designated in the processing of a main routine, a program analyzing circuit 5 supplies the variable number to a variable referring means 6; and if it is necessary to substitute a numerical value into the variable, the circuit 5 supplies the variable number and the numerical value to a variable writing means 7. The variable referring means 6 understands the variable number as an address of a memory 8 and refers to the memory 8 directly to read out the numerical value in this address and transfers it to the processing of the main routine. The variable writing means 7 uses the variable number supplied from the analyzing circuit 5 as an address of the memory 8 to write the numerical value in this address. A control signal output circuit 10 outputs the operation processing result of the analyzing circuit 5 to an object 3 to be controlled.</p> |
