[en] This report describes the application of the VMEC (Variational Moments Equilibrium Code) and PROCTR (PRedictOr Corrector TRansport code) numerical codes to the W7-AS experiment. The different versions of VMEC, each of which has been used for W7-AS and CHS (National Institute for Fusion Science, Nagoya, Japan), were compared to confirm their reliability and performance, and successfully benchmarked. The PROCTR code set was installed in the Wendelstein-VAX cluster. Its potential in experimental interpretation and theoretical analysis was demonstrated for coordinate inversion based on full 3-D geometry, power balance analysis and time-dependent transport simulation. The benchmark tests of tools for finite-β equilibrium and power balance analysis are a prerequisite for the joint profile and configuration database for stellarators which has just been started. We successfully recognized the compatibility of the schemes used on W7-AS and CHS. (orig.)
