the blas wrapper does not do full checking of its arguments
furthermore, the checking could be shared with the cblas routines via macros, to ensure consistency.

Attached I send the second version (partial, only for level 2 routines with
standard 4 prefixes (S, D, C, Z)). I have used submacros as we discussed in
recent mails. I think that we must pass to submacros the variable 'pos' for
"return" the result and the position 'posIfError' as the "returned" value if
an error occurs.
But we need some trick for check with macros the parameter 'lda', because
the check is different depending on 'order' parameter and involves other
arguments like 'M' and 'N'. Probably, this check must be done explicitly.
