Method for executing a computer program in a computer network, in particular in order to control a microscope

A method for executing a computer program, comprising the following steps:

• providing a computer network that has at least two computers connected to one another via a network, each having its own main memory per computer,
• providing multiple different images of execution environments, each of which has a respective executable module, wherein each of these modules provides a respective function, and the execution environment containing this module is executable on at least one of the computers in a namespace of its own, wherein the module calls an operating system core of the relevant computer, and this work environment returns a value that is output by this module as the result of the function provided thereby,
• receiving a computer program that has at least a) a first instruction, which calls a first function that returns a first result value, b) a second instruction, which contains a condition on the basis of the first result value, and c) a third instruction, which calls a third function,
• starting an execution environment with the module providing the first function, and receiving the return value thereof as first result value,
• checking the condition indicated in the second instruction,
• ascertaining that the condition is satisfied, and starting an execution environment with the module providing the third function.

A method for translating a computer program from one representation into another representation, in particular into a machine-executable representation, comprising the following steps:

• providing a computer network that has at least two computers connected to one another via a network, each having its own main memory per computer,
• providing a database that contains multiple different execution environments, each of which having a respective executable module, wherein each of these modules provides a respective function, and the execution environment containing this module is executable on at least one of the computers in a namespace of its own, wherein the module calls an operating system core of the relevant computer, and this work environment returns a value that is output by this module as the result of the function provided thereby, wherein the database contains, in addition to each of the modules, an interface definition of its own that describes the function provided by the relevant module, and is connected to the network,
• reading in a computer program that has at least a) a first instruction, which calls a first function that returns a result value, and b) a second instruction, which calls a second function with the received result value of the first function as a parameter,
• reading in a first interface definition of a first module providing the first function, wherein the first interface definition describes the first function by virtue of its containing at least one data type of its result value, from the database,
• reading in a second interface definition of a second module providing the second function, wherein the second interface definition describes the second function by virtue of its containing at least one data type of a parameter of the second function, from the database, and
• comparing the data type of the result value of the first function with the data type of the parameter of the second function,
• ascertaining inequality between the two data types, and
• sending an error to an input apparatus and/or terminating the translation process.
