Section 8. Processing and Math Instructions

Randomize (Number)

Initializes the random-number generator.

Syntax

Randomize (Number)

Remarks

The argument number can be any valid numeric expression. Number is used to

initialize the random-number generator by giving it a new seed value. If you

omit number, the value returned by the Timer function is used as the new seed

value.

If Randomize is not used, the Rnd function returns the same sequence of

random numbers every time the program is run. To have the sequence of

random numbers change each time the program is run, place a Randomize

statement with no argument at the beginning of the program.

RealTime

Used to pick out year, month, day, hour, minute, second, usecond, day of

week, and/or day of year from the CR800 clock.

Syntax

RealTime(Dest)

Remarks

The destination array must be dimensioned to 9.

RealTime Example

This example uses RealTime to place all time segments in the Destination array. If

the remark (‘) is removed from the first 8 Sample statements and the last Sample

statement is remarked, the results will be exactly the same.

Public rTime(9) 'declare as public and dimension rTime to 9

Alias rTime(1) = Year 'assign the alias Year to rTime(1)

Alias rTime(2) = Month 'assign the alias Month to rTime(2)

Alias rTime(3) = Day 'assign the alias Day to rTime(3)

Alias rTime(4) = Hour 'assign the alias Hour to rTime(4)

Alias rTime(5) = Minute 'assign the alias Minute to rTime(5)

Alias rTime(6) = Second 'assign the alias Second to rTime(6)

Alias rTime(7) = uSecond 'assign the alias uSecond to rTime(7)

Alias rTime(8) = WeekDay 'assign the alias WeekDay to rTime(8)

Alias rTime(9) = Day_of_Year 'assign the alias Day_of_Year to rTime(9)
