Is this syntax ok?
Code:
r4c7/c9=5 => r2c7<>7

It doesn't make any sense to me.

My solver finds a short chain for this elimination, but it includes the value <3>, which isn't in your syntax.

Is this better?
Code:
r4c7/c9=5:
r4c7=5 => r2c7(=3)<>7
r4c9=5 => r3c9=7 => r2c7<>7

I have now learned from tlanglet that can be written as follows:
Code:
(7=5)r3c9-(5)r4c9=(5-3)r4c7=(3)r2c7; r2c7<>7

Thank's a lot!
