Caché ObjectScript FunctionsParametersrangeA nonzero positive integer used to calculate the random number. The number returned isbetween zero and the value of range-1. It can be a nonzero positive integer value, the nameof an integer variable, or any valid Caché ObjectScript expression that evaluates to a nonzeropositive integer.ExamplesThe following example returns a random number from 0 through 24 (inclusive).WRITE $RANDOM(25)To return a random number with a decimal portion, you can use the concatenation operator(_) or the addition operator (+), as shown in the following example:SET x=$RANDOM(10)_$RANDOM(10)/10WRITE !,xSET y=$RANDOM(10)+($RANDOM(10)/10)WRITE !,yThis program returns numbers with one decimal position, ranging between .0 and 9.9(inclusive). Using either operator, Caché deletes any leading and trailing zeros (and the decimalpoint, if the decimal portion is zero). However, if both $RANDOM functions returnzero (0 and .0), Caché returns a zero (0).The following example simulates the roll of two dice.DiceWRITE !,"Do you want to roll the dice?"WRITE !, "Press to exit"READ !,"Roll Dice",AQUIT:A=""WRITE !,$RANDOM(6)+1,"+",$RANDOM(6)+1GOTO Dice294 Caché ObjectScript Reference
