Concatenating Variables with PREFIX

[djbateman]

I have an unknown number of variables that have the same prefix for the variable name.  I want to concatenate all the fields into a single field separated by a semi-colon.  Is there a simple notation to do something like:

catx('; ', code:)

I could create a macro variable that gets the number of variables and then just do:

catx('; ', of code1-code&ncodes.)

but I thought I would see if there is a simpler notation.

You can do that, however ...

Since code: also refers to a list of variables, you still need to add "of":

catx('; ', of code:)
