Claims (4)

1. What we claim is:~ lo A digital computer comprising a processor, a main store for containing digital data in the form of statements comprising operators and parameters in a compacted high level language as hereinbefore defined, a statement store, a parameter store, means automatically-operative to transfer operators or alternatively operators and parameters from the main store to the statement store, means automatically operative to transfer parameters from the main store to the parameter store in the sequential order in which they appear in the statement, sequence decode logic which automatically examines the operators in the statement store to determine their priority levels, a sequence store receiving the output of the sequence decode logic so as to automatically store the operators in accordance with their assigned priorities and a micro programme arrangement settable automatically in dependence upon the content of the sequence store and operative automatically to control the processor to process digital data automatically supplied thereto under the control of the parameter store and in accordance with the micro programme set up in the micro programme arrangement.

2. A digital computer comprising a processor, a main store for containing digital data in the form of statements comprising operators and parameters in a compacted high level language as hereinbefore defined, the operators and 4 parameters being of variable length coding, said length being determined by the amount of usage to which the operators and parameters are to be subjected and being in general of length inversely related to the amount of usage as aforesaid, a statement store, a parameter store, means automatically operative to transfer operators, or operators and parameters, of variable length from the main store to the statement store, means automatically -operative to transfer parameters of variable length from the main store to the parameter store in the sequential order in which they appear in the statement, sequence decode logic which automatically examines the operators in the statement store to determine their priority levels, a sequence store receiving the output of the sequence decode logic, so as to automatically store the operators in accordance with their assigned priorities and a micro programme arrangement settable automatically in dependence upon the content of the sequence store and operative automatically to control the processor to process digital data automatically supplied thereto under the control of the parameter store and in accordance with the micro programme set up in the micro programme arrangement „

3. , Digital computer as claimed in claim 1 or 2 and which has parameter decode logic operative to detect successive parameter units between operators in order to automatically determine the number of parameter units employed to form a parameter,

4. -„ A digital computer as claimed in claim 35 in which the parameter decode logic shares common elements with the sequence decode logic „ 5° A digital computer substantially as hereinbefore described with reference to the accompanying drawings toi&ey for App icants
