                        **********


[SYMPTOM]
     Spurious ?SCNIFL errors can occur while processing .TMP
or  indirect  files  and  the  user's  default path includes
SFD's.

                        **********


[DIAGNOSIS]
     There are several cases in  which  SCAN  looks  up  its
input  indirect  file  a number of times.  However, when the
LOOKUP is to the user's default path, the monitor  puts  the
PPN  portion  of  the  path  in the .RBPPN word of the file.
Subsequent LOOKUPs fail, because  the  default  path  is  no
longer being referenced.

                        **********


[CURE]
     Always restore  the  given  PPN  immediately  after  an
indirect file lookup.

[SYMPTOM]
 
 
 
 
     The command string /XYZ:( value1 , value2 ) produces an
error  message,  while  the  command  string  /XYZ:(value1 ,
value2 ) works correctly.
 

                        **********


[DIAGNOSIS]
 
     There is no leading  blank  suppression  done  at  that
point.
 

                        **********


[CURE]
 
     Make the multiple  switch  value  processor  consistent
with  itself  and  allow leading blanks after the "(".  Note
that /XYZ:  value1 is treated differently, in that it  means
/XYZ,  then  process  file "value1".  The consistency within
multiple switch value processing is thought to  be  somewhat
more  important  than  any further inconsistencies this edit
may introduce  between  single  and  multiple  switch  value
processing.
