Roll you own DTR to get around the DINTs.
The COP instruction is the wrong instruction for this. Use FLL instead.
NEQ N7[200] N7[201] MOV N7[200] N7[201] FLL 0 N[N7[200][0] 10
If you are unfamiliar with the mnemonics then copy the line above and insert a blank rung. Double click the rung number and a text entry field will pop up at the top of your ladder. Paste the copied rung in and hit enter, you'll see the rung.
Here is what it should look like
-+-NEQ-----------+----+-MOV-----------+----+-FLL-----------+
|A N7[200]| |SRC N7[200]| |SRC 0|
|B N7[201]| |DEST N7[201]| |DEST N7[200][0]|
+---------------+ +---------------+ |LEN 10|
+---------------+
Also, you might want to check the way the PLC5 files were translated. It looks like the PLC/5 program used indirection to specify a file number. If this is the case then you are going to have to redefine all your tags that are prefixed with a N into a 2D array or you are going to have to bite the bullet and do it the right way and rewrite the program for CLX instead of using the translator.
In the CLX N7, N9, N10, etc are the tag names of arrays. The numbers 7,9, and 10 are part of the array tag name, they are not an index-able address. If the PLC/5 used indirect addressing on the file number then you have to define an array N[3][200] to get three index-able columns in the array. Now all N7 addresses will translate to N[0][???], N9 addresses translate to N[1][???], and N10 addresses translate to N[1][???].
If that is the case then you will not be able to do this without altering the HMI.
