I
totally agree with you about UM sharing his efforts. Thank you
UM!!

What
are you sharing Chuck, sarchasm? You don't seem to be interested in
sharing any of your code. And to think I had volunteered to do something for
you.

[amibroker] Re: Additions to ABtool v0.0.5 beta
I
see the beta releases of ABTool and AmiBroker similar in that the developers
in both cases are anxious to share their efforts with us at the earliest
opportunity. The downside to us is that every "i" hasn't been
dotted and the documentation tends to lag. To be critical of
this method of software distribution, however, might mean that we don't see
such software and/or enhancements until they
are "finished". I prefer to see things just as
they are I'm sure many others here share that sentiment.

of us are already making use of the software. That's as close to
heaven as I'm likely to get in my lifetime.

Re: Additions to ABtool v0.0.5 betaThanks for the
confidence.For folks that have done C++ or similar programming,
concepts like "\n" are probably cake as are the fact that "," can't be
added behind numbers in FileWriteNum statements and I know this is beta,
but even for those that have done their share of programming in
unrelated languages in the past there isn't enough info to keep this
from initially being a semi-painful experience. --- In
