Error: Keyword argument requires explicit interface for procedure 'bar_pwrk' at

If 'Call bar_pwrk(pr,p,f,cd,info,work=aux)' is replaced by 'Call
foo_pwrk(pr,p,f,cd,info,work=aux)' the error disappears. Note that I did not
write the code, but only kept it and I don't know if the code is valid or not.
