INF
The Inf internal function returns the largest possible number in Business Rules! on the current system. For current DOS, Network, Unix and Linux systems, Inf is 1.000000E+307. To find the smallest number, use PRINT 1/INF.
Comments and examples
00010 print inf ! prints the largest number in BR 00020 print 1/inf ! prints the smallest number in BR
Inf may be used to append more characters to the end of a string
To append string2$ to string1$ means to join string2$ to the end of string1$.
To append to the end of a String you should (for maximum speed of code execution) use
X$(inf:0)="append this to end"
OR
X$(inf:inf)="append this to the end"
Here, inf denotes infinity.
So X$(inf:inf) means "the substring of X$ starting at infinity". This is particularly useful when you don't know how long your string is and do not want to calculate its length.
