Re: [amibroker] Re: OLE/COM: Support StaticVarSet/Get/Remove (and StaticVarSet/GetText as well)

There are many uses for passing variables between JScript/_vbscript_ and AFL. One example I am doing now is passing an external value to an Exploration to do position sizing. Another example is that I need to pass values to an AFL to overwrite Param value. One more example is that an AFL needs to know from which JScript it is invoked and then behave differently. As you said, we can use file to pass data. In fact that's what I am doing now. However, it is becoming more cumbersome when you do it a lot and the code becomes not as clean as I would like it to be. So, it would be natural to use StaticVarSet/Get instead. AFL engine has supported StaticVarSet/Get as a means to record states and pass data between different runs. It is very logical to enable AA Object to do so.   ----- Original Message ----- From: Fred To: amibroker@yahoogroups.com Sent: Friday, September 15, 2006 12:16 PM Subject: [amibroker] Re: OLE/COM: Support StaticVarSet/Get/Remove (and StaticVarSet/GetText as well) It is difficult to comment on the AB enhancement you are suggesting as I don't know the context ... If all you are wanting to do is communicate some info between VBS and AFL and you aren't wanting to run the AFL 10 times a second then this is easy enough to do using FSO to write a file from VBS and then use Direct I/O ( fOpen / fGets / fClose ) in AFL. --- In [EMAIL PROTECTED]ps.com, "Mark H" <[EMAIL PROTECTED]..> wrote: > > It is not surprising to me that the author of BatMan and IO uses some scripting :-) > > ----- Original Message ----- > From: Fred > To: [EMAIL PROTECTED]ps.com > Sent: Friday, September 15, 2006 11:29 AM > Subject: [amibroker] Re: OLE/COM: Support StaticVarSet/Get/Remove (and StaticVarSet/GetText as well) > > > LOL ...
