Recording medium and programming support apparatus

A programming support apparatus that provides support for generation of an operational program for operating a programmable controller, the programming support apparatus comprising:

• processing circuitry to
• acquire a first source code of the operational program, wherein the first source code contains definitions of first function blocks corresponding to non-object-oriented subroutines,
• receive a user selection of function blocks among the first function blocks of the first source code;
• receive a user selection of variables to be integrated into a common variable among variables of the selected function blocks;
• and
• generate a second source code of the operational program by replacing a plurality of first function blocks of the first function blocks described in the first source code with a second function block, the second function block describing the function as a plurality of methods, wherein
• the second source code contains definitions of object-oriented function blocks,
• the processing circuitry receives relationship information indicating a relationship between the variable of each of the plurality of first function blocks to be integrated into the common variable and a common variable of the second function block that is the common variable, and
• the processing circuitry generates the second source code based on the relationship information by replacing the plurality of first function block selected from the first source code with the second function block containing the methods corresponding to the plurality of first function blocks.

A non-transitory computer-readable recording medium storing a programming support program for a computer that provides support for generation of an operational program for operating a programmable controller, the programming support program causing the computer to:

• acquire a first source code of the operational program, wherein the first source code contains definitions of first function blocks corresponding to non-object-oriented subroutines;
• receive a user selection of function blocks among the first function blocks of the first source code;
• receive a user selection of variables to be integrated into a common variable among variables of the selected function blocks;
• and
• receive relationship information indicating a relationship between the plurality of first function blocks and a second function block and a relationship between the variable of each of the plurality of first function blocks to be integrated into the common variable and a variable of the second function block that is the common variable and to generate a second source code of the operational program based on the relationship information by replacing a description relating to first instances declared based on the plurality of first function blocks in the first source code, with a description relating to a second instance declared based on the second function block, the second function block describing the function as a plurality of methods,
• wherein the second source code contains definitions of object-oriented function blocks.
