Euphoria is NOT easier to code as advertised. I'm used to pascal conventions
where there are exactly two types of read and write statements not C styled
incoherance.
Euphoria seems to be a cross between "wanna-don't-wanna be" C and TCL without
TK and almost C and TCL/TK with the addition of David Cuny's Win32lib. I
believe the TCL/TK expr command does support 32 bit bitwise operators. Sorry...
Just frustrated....

Yes the RNG appears to be good for everyday purposes BUT p=.500000 for all
tests is the optimum. Consistant scores of p>=.9000 or p<=.10000 are not good.
If the end objective of using the rand() function REQUIRES uniformly generated
random numbers the results I saw did not indicate Euphoria passed all of the
tests.
Maybe RDS might like to weigh in and state the source and/or type of RNG that
is coded into Euphoria.
