摘要:
Conventionally, when executing a plurality of programs while being synchronized by a plurality of debuggers, an interface has been required for performing a particular coordination between the debuggers. In the present invention, programs are synchronously executed without coordination between the debuggers by performing a control method including a step for maintaining a program execution state in the debuggers to be different from an actual program execution state, so that the program execution is retained, if necessary, in response to a program execution request from a debugger.

A lock apparatus includes a operation handle, a pair of springs movably supported by the container member, a pair of slide pins urged in directions of lock holes defined on the support member by the springs, respectively, and a pair of cam members to which rear end portions of the slide pins are fitted, respectively, to urge each slide pin to project and retract. When the operation handle is operated in a swing manner, a front end portion of each slide pin is retracted from each lock hole of the support member against pressure of each spring. Engagement holes are defined on opposed surfaces of each front end portion of the cam member having a cylindrical shape. Each rear end portion of the slide pin is formed in a bifurcated structure to have elastic pieces. Each of elastic pieces has a protrusion for detachably engaging with each of engagement holes.
