Instructing the use of application programming interface commands in a runtime environment

A computer system for instructing the use of application programming interface (API) commands in a runtime environment, comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
• receiving, by a computer processor, a source code with a high level language API command;
• accessing, by a computer processor, metadata for the source code;
• applying, by a computer processor, an instruction included in the metadata to the high level language API command;
• and
• processing, by a computer processor, the high level language API command to a low level code using a command translator based, at least in part, on the metadata.

A computer program product for instructing the use of application programming interface (API) commands in a runtime environment, comprising:

• one or more computer-readable storage media and program instructions stored on at least one of the one or more tangible storage media, the program instructions executable by a processor to cause the processor to perform a method comprising:
• receiving, by a computer processor, a source code with a high level language API command;
• accessing, by a computer processor, metadata for the source code;
• applying, by a computer processor, an instruction included in the metadata to the high level language API command;
• and
• processing, by a computer processor, the high level language API command to a low level code using a command translator based, at least in part, on the metadata.
