Hola.

Maybe you need \commalistsentence?

\def\Autores{%
  {Luis David Gómez-Méndez, Ph. D.},
  {Adriana del Pilar Pulido-Villamarín, M. Sc.},
  {Rubiela Castañeda-Salazar, M. Sc.},
  {Juan Carlos Ulloa-Rubiano, Ph. D.},
  {Adriana Matiz-Villamil, M. Sc.},
  {Fidson Juarismy Vesga-Pérez, Ph. D}%
}
\starttext
\commalistsentence[\Autores][{;\space},{\space\letterampersand\space}]
\stoptext

Best regards,

I'm trying to produce a document with several authors, using macros for comma separated lists. My MWE is as follows: 

%%%%%%%%%%%%%%%%%%%%%%
\def\autores{%
  {Luis David Gómez-Méndez, Ph. D.},
  {Adriana del Pilar Pulido-Villamarín, M. Sc.},
  {Rubiela Castañeda-Salazar, M. Sc.},
  {Juan Carlos Ulloa-Rubiano, Ph. D.},
  {Adriana Matiz-Villamil, M. Sc.}%
}

\def\lastAutor{Fidson Juarismy Vesga-Pérez, Ph. D}

\def\autorParaLista#1{#1;\space}
\def\listaAutores{\processcommacommand[\autores]\autorParaLista & \lastAutor: autores.}

\starttext

\listaAutores

\stoptext
%%%%%%%%%%%%%%%%%%%%%%%

So far, no luck trying to extract the last item from a comma separated list. That's the reason I created a "\lastAutor" macro, so I can treat the last one differently. 

This produces: 

%%%%%%
Luis David Gómez-Méndez, Ph.D.; Adriana del Pilar Pulido-Villamarín, M. Sc.; Rubiela Castañeda-Salazar, M. Sc.; Juan Carlos Ulloa-Rubiano, Ph.D.; Adriana Matiz-Villamil, M. Sc.; & Fidson Juarismy Vesga-Pérez, Ph.D: autores.
%%%%%%

However, what I'm trying to get is: 

%%%%%%
Luis David Gómez-Méndez, Ph.D.; Adriana del Pilar Pulido-Villamarín, M. Sc.; Rubiela Castañeda-Salazar, M. Sc.; Juan Carlos Ulloa-Rubiano, Ph.D.; Adriana Matiz-Villamil, M. Sc. & Fidson Juarismy Vesga-Pérez, Ph.D: autores.
%%%%%%

Which is very close to what I need, except the ";" just before the "&". So the question is: is it possible to do this in a more effective or simpler, or better way, and write a macro that outputs something like "Author1; Author2; Author3 & Author4: authors.", given a comma separated list of authors?

“You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.
