While translating the code to lite-c, I am confronted with a problem:

If I leave the following lines like they are, I will get the error message "Error in line 138: 'enable_click': is not a member of 'ENTITY'".

Code:
my.enable_click = on;
my.enable_entity = on;
my.enable_block = on;


But if I change them to the following lines, I will get the error message "Error in line 138: syntax error".

Code:
my.ENABLE_CLICK = ON;
my.ENABLE_ENTITY = ON;
my.ENABLE_BLOCK = ON;


Can somebody help me?
