Chemical process machine programming system

In a system comprising a computer for controlling a membrane filtration process, wherein a memory of the computer contains an operation comprising plurality of executable steps in the process, and wherein the plurality of executable steps comprises at least one variable step and at least one fixed step, a method comprising steps of:

• (A) receiving input from a user indicating a modification to the at least one variable step;
• and
• (B) modifying the at least one variable step to reflect the input received from the user in step (A).

In a system comprising a computer for controlling a membrane filtration process, wherein a memory of the computer contains an operation comprising a plurality of executable steps in the process, and wherein the plurality of executable steps comprise at least one variable step and at least one fixed step, an apparatus comprising:

• means for receiving input from a user indicating a modification to the at least one variable step;
• and
• means for modifying the at least one variable step to reflect the input received from the user.

In a system comprising a computer for controlling a membrane filtration process, wherein a memory of the computer contains a procedure data structure comprising pointers to a plurality of operation data structures, and wherein each of the plurality of op ration data structures comprises at least one fixed step in the process and at least one variable step in the process, a method comprising steps of:

• (A) providing to a user of the system a first interface through which user may select one of the plurality of operation data structures;
• and
• (B) providing to the user a second interface through which the at least one variable step, but not the at least one fixed step, of the selected operation data structure may be modified.

In a system comprising a computer for controlling a membrane filtration process, wherein a memory of the computer contains a procedure data structure comprising at least one pointer to at least one operation data structure, and wherein the at least one operation data structure comprises at least one fixed step in the process and at least one variable step in the process, a method comprising steps of:

• (A) receiving input from a user indicating a modification to the at last one variable step;
• and
• (B) modifying the procedure data structure to reflect the input received from the user in step (A).

In a system comprising a computer for controlling a membrane filtration process, wherein a memory of the computer contains a procedure data structure comprising at least one pointer to at least one operation data structure, and wherein the at least one operation data structure comprises at least one fixed step in the process and at least one variable step in the process, an apparatus comprising:
