Abstract
A new proof for the existence of formal fundamental solutions of meromorphi c systems of linear ordinary differential equations is given. The proof is presented in a totally constructive form. Moreover, we give a corresponding proof of existence for highest level formal solutions. (C) 1999 Elsevier S cience Inc. All rights reserved.
