The IUE high dispersion spectra available in NEWSIPS MXHI format of IUE final archive can not be directly analyzed in IRAF. A number of different packages like IUEDR (part of Starlink) or IUERDAF (written in IDL) has usually been used for this purpose. However, with the combination of external IRAF package iuetools and several home-written cl scripts a batch analysis of a large number of spectra can be performed. We describe in detail the whole process of obtaining the data, conversion to IRAF format, echelle orders merging and continuum fitting up to the measurements of radial velocity of selected resonance lines. We also give a hints for rapid preparing of a convenient plot of line profile series ordered by time and orbital phase. In conclusions, a brief discussi on of advantages and bottlenecks of IRAF approach in regards of other packages is given.
