RANDOM
Random generator
The basis of the random generator in Litos8 system is generation of pseudo-random sequence of numbers using calculation new_seed = old_seed*17405 + 10395331. Unlike conventional algorithms, the calculation carried out 64-bit with exchanging double word operands, thus ensuring sufficient diversity of random numbers, with huge repeat interval. Moreover, number generator can be wobbled with unforeseeable events, such as pressing a key.
RandInit - initialize random generator
INPUT:
DX:AX = new random generator seed
BL = flag, 0 = use pseudorandom sequence, 1 = enable events
RandShift - shift random generator with an event
INPUT:
AX,BX,CX = shift random value
RandByte - get random byte
OUTPUT:
AL = random byte (0 to 0ffh)
RandWord - get random word
OUTPUT:
AX = random word (0 to 0ffffh)
RandDWord - get random dword
OUTPUT:
DX:AX = random double word (0 to 0ffffffffh)
RandByteMax - get random byte with max value
INPUT:
AL = maximal unsigned value (0 to 0ffh)
OUTPUT:
AL = random byte (0 to maximal value)
RandWordMax - get random word with max value
INPUT:
AX = maximal unsigned value (0 to 0ffffh)
OUTPUT:
AX = random word (0 to maximal value)
RandDWordMax - get random dword with max value
INPUT:
DX:AX = maximal unsigned value (0 to 0ffffffffh)
OUTPUT:
DX:AX = random double word (0 to maximal value)
RandSByteMax - get random signed byte with max value
INPUT:
AL = maximal signed value (-128 to +127)
OUTPUT:
AL = random byte (0 to maximal value)
RandSWordMax - get random signed word with max value
INPUT:
AX = maximal signed value (-32768 to +32767)
OUTPUT:
AX = random word (0 to maximal value)
RandSDWordMax - get random signed dword with max value
INPUT:
DX:AX = maximal signed value (-80000000h to +7fffffffh)
OUTPUT:
DX:AX = random double word (0 to maximal value)
RandByteInt - get random byte in interval
INPUT:
AL = maximal value (unsigned)
AH = minimal value (unsigned)
OUTPUT:
AL = random byte (min to max)
RandWordInt - get random word in interval
INPUT:
AX = maximal value (unsigned)
DX = minimal value (unsigned)
OUTPUT:
AX = random word (min to max)
RandDWordInt - get random dword in interval
INPUT:
DX:AX = maximal value (unsigned)
BX:CX = minimal value (unsigned)
OUTPUT:
DX:AX = random double word (min to max)
RandSByteInt - get random signed byte in interval
INPUT:
AL = maximal value (signed)
AH = minimal value (signed)
OUTPUT:
AL = random byte (min to max)
RandSWordInt - get random signed word in interval
INPUT:
AX = maximal value (signed)
DX = minimal value (signed)
OUTPUT:
AX = random word (min to max)
RandSDWordInt - get random signed dword in interval
INPUT:
DX:AX = maximal value (signed)
BX:CX = minimal value (signed)
OUTPUT:
DX:AX = random double word (min to max)
