Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
111 words
In an electronic computer system which automatically carries out initial program loading in response to an externally given signal, an improvement comprising means for inhibiting the initial program loading which would otherwise be carried out in response to said externally given signal, and means for designating an alternative operation to be carried out in place of said initial program loading in response to said externally given signal, said initial program loading inhibiting means being constructed such that it permits the initial program loading to be achieved when said alternative operation designating means does not designate the alternative operation in a predetermined time period after the application of said externally given signal.
