 I have a problem when I load a sequential file into an array.  It seems
 to be a C64 bug.  After loading the data from the sequential file into
 an array, the program works find for awhile until suddenly, for no
 apparently reason, the program stops for 10-20 seconds then continues
 as if nothing happened.  After studying this problem, I have discovered
 how to reproduce it. 

   1.  Create a sequential file
   2.  Read the file into an array and print the amount of remaining
       RAM.
       Example:

100    DIMENSION ARRAY$(500)
200    T$="0:FEB 86,S,R"
250    OPEN 15,8,15
300    OPEN 4,8,4, T$
400    FOR I=1 to 200
500    INPUT#4,ARRAY$(I)
600    IF ST>0 THEN 800
700    NEXT I
800    X=TI:PRINT" READ COMPLETE":PRINT" AVALILABLE RAM IS"
900    PRINT FRE(O) - (SGN(FRE(O)) < 0)*65535 :REM  THIS IS THE DELAY
910    Y=(TI-X)/60: PRINT" TIME DELAY=";Y
920    PRINT" STOP PROGRAM"
930    CLOSE4: CLOSE15
940    STOP
950    END
	
 The larger the loop, the longer the execution delay.  It seems the BASIC
 array or memory pointers get confusioned.

 Thanks in advance
