INSTRR() 

   - PCBoard has a bug with the undocumented function INSTRR, it always
     returns 1 more than the value it should.

   - Frontier returns the real value

CHATSTAT()

   - PCBoard returns Chat Status from the logged user, even if a GetAltUser
     has been issued.

   - Frontier returns Chat Status from the loaded user. This means it will
     be the logged user if no GetAltUSer as been performed or if a FreAltUser
     is used to load back the logged user.

USELMRS, USELMRS()

   - PCboard allows one to specify not to load Last Message Read pointers
     when using GetAltUser, this is supposed to save memory if you don't
     need those informations.

   - Due to the memory management difference between PCboard & Frontier,
     Frontier does not need this. You'll have access to LMR wherever you
     are, not consuming more memory than usual.

     USELMR will be ignored, and USELMR() will always return TRUE

CALL

   - PCBoard's CALL statement does not support arguments
   - Frontier's CALL statement does support arguments. ie:
     CALL "C:\PP\MYPPE.PPE /O /L:3"
   - Upon returning from a CALL'ed PPE, no reset to "StartDisp FCL" is
     made. PCBoard force line couting mode each time a PPE ends, but
     this is only more difficult for PPE coders to make clean work
     (for example in frontier when the Timehook.ppe executes in the middle
     of a PPE, this PPE may assume lines couting is off. When returning
     it would issue "More?" prompts while it thinks it can rely on the
     "Startdisp FNS" it used at the beginning of itself.
