result:=(randseed*a+b) mod $7fffffff;
randseed:=result;
a和b分别是多少？
从下面的代码看，好像a==$8088405？但是b是多少？？

procedure _RandInt;
asm
{ ->EAX Range }
{ <-EAX Result }
PUSH EBX
{$IFDEF PIC}
PUSH EAX
CALL GetGOT
MOV EBX,EAX
POP EAX
MOV ECX,[EBX].OFFSET RandSeed
IMUL EDX,[ECX],08088405H
INC EDX
MOV [ECX],EDX
{$ELSE}
XOR EBX, EBX
IMUL EDX,[EBX].RandSeed,08088405H
INC EDX
MOV [EBX].RandSeed,EDX
{$ENDIF}
MUL EDX
MOV EAX,EDX
POP EBX
end;

procedure _RandExt;
const two2neg32: double = ((1.0/$10000) / $10000); // 2^-32
asm
{ FUNCTION _RandExt: Extended; }

PUSH EBX
{$IFDEF PIC}
CALL GetGOT
MOV EBX,EAX
MOV ECX,[EBX].OFFSET RandSeed
IMUL EDX,[ECX],08088405H

{$ELSE}

IMUL EDX,[EBX].RandSeed,08088405H

MOV [EBX].RandSeed,EDX
{$ENDIF}

FLD [EBX].two2neg32
PUSH 0
PUSH EDX
FILD qword ptr [ESP]
ADD ESP,8
FMULP ST(1), ST(0)
POP EBX
end;
