Straightforward program aimed at deriving the chemical composition of post-AGB stars in 6 globular clusters of various metallicities ([Fe/H] from -1.0 to -2.2) in order to study the nucleosynthesis, mixing and mass loss processes in low mass metal-poor evolved stars. No special requirement, except that 2 pairs of stars (cf README) should be preferentially observed during the same night (NGC5986-ID6 and -ID7; NGC6656-4 and -5). New OBs (and FCs+README) available from May 2002. PLEASE, disregard constraint Moon_phase=0.7 as specified in OBs (it should be =1.0).
