[MX V8i SS3] Haul mass analysis limitation

Hello,

I've encounter a bug or unknown to me limitation (no such info neither in "User manual" nor in "Command Language Reference"). When the number of point in haul analysis exceeds 1000 (10km with 10m step), a window appears with buggy information:

"MX Error E0097: Invalid string name specification"

Part of working input (1000 points):

HAUL,A1 QUANT,A1
070,1=MC10,      ,3=VM00,4=10,5=426500,8=436490
071,      ,2=VOLU,           ,5=426500,8=436500
071
072,1=MC10,2=VM00,3=VH00,    ,5=426500,8=436490
075
999

Part of not working input (1001 points)

HAUL,A1 QUANT,A1
070,1=MC10,      ,3=VM00,4=10,5=426500,8=436500
071,      ,2=VOLU,           ,5=426500,8=436500
071
072,1=MC10,2=VM00,3=VH00,    ,5=426500,8=436500
075
999

Is it right or something is wrong? I haven't used is before - spreadsheet did it ;)

Best regards
