I am a learner of VASP. When I run some examples downloaded from http://cms.mpi.univie.ac.at/vasp-worksh ... tation.htm
It always followed by the following words,

vasp.4.6.12 27Jun03 complex
POSCAR found : 1 types and 2 ions
PGFIO-F-225/list-directed read/unit=10/lexical error-- unknown token type.
File name = POTCAR formatted, sequential access record = 52
In source file pseudo.f, at line number 227


or,

vasp.4.6.12 27Jun03 complex
ERROR: there must be 1 or 3 items on line 2 of POSCAR
FORTRAN STOP


I think the examples downloaded should be feasible. What's wrong? Edition incompatible? Thanks.

This error message is due to a reading error. Sometimes, it
shows up of file formats are conflicting, like hidden characters in a file (POSCAR in your case)
e.g.: the 'end-of the line' ctrl M character causes a read erron on unix.
All VASP-workshop examples were generated an run on Unix
machines. Please check whether the files are ok after you downloaded and unzipped them.
