Euler pseudoprime/Code

The following Sourcecode is the Heart of all calculating fermat pseudoprime-, euler pseudoprime- and strong pseudoprime programs:

/* REXX-Programm */
say 'Only a Library!'
exit 1
/* */
/* */
m_u: procedure
  arg a,l,m
/* initialisierung */
  as = a
  ai = a
  li = (l-1)
  DO li
    a = a * ai
    a = a // m
  END
return a
