'$' isn't a legal Fortran character (nor is it allowed in a Matlab variable name); you'll have to fix that up. I don't know whether your code page caused a translation error in pasting the code or whether the code may have been run through a preprocessor and those references replaced by some other character or sequence of characters but you'll need whatever that is resolved.
Other than that, it is essentially Matlab syntax with the substitution of lowercase and end instead of ENDIF
