FormNotifyForm Question

Print Post Print Post  
I have noticed that if FormNotifyForm is set to 2 in one event, and also set to 1 in another, @FormNotifyForm returns 3.

I guess that makes sense, but when I see a 3, the manual tells me I should expect it to mean "Allow save, prohibit record retreat". How can I determine that 3 means one "2" setting and one "1" setting?

@FormNotifyForm and @NotifyForm return the actual "flag set" in binary:

1 = 00000001 ; flag one set
2 = 00000010 ; flag two set
3 = 00000011 ; both flag one and two set

To check for values as set by either NotifyForm or FormNotifyForm, you should use @FormIsNotifyForm or @IsNotifyForm.

use @FormIsNotifyForm or @IsNotifyForm

Thanks, Mark. That was easy.

Now that you point it out, I see it is listed right above NotifyForm on page 36 of the programming guide. I was using the logic of:  If I use NotifyForm to set a value, I should simply use the same name with an "@" symbol in front of it (@NotifyForm) to check for that value. Roll Eyes

I see now that I should have at least been checking to see if @NotifyForm() > 0, rather than if @NotifyForm() = 1. But @IsNotifyForm is even more appropriate for what I want.

Thanks again. Smiley

NotifyForm(n) tells Sesame to set the n'th flag, combining (boolean OR'd together) it with any that have already been set.

@NotifyForm() asks Sesame which flags, in combination, have been set - returning the sum (boolean OR'd value).

@IsNotifyForm asks Sesame if a particular (and singular) flag has been set (boolean AND).

So NotifyForm and @NotifyForm are actually the complements of one another, even though NotifyForm and @IsNotifyForm share the same numeric notation.

To decode the results from @NotifyForm:

NotifyForm(1) = 00000001 = 1 ; post disabled
NotifyForm(2) = 00000010 = 2 ; advance disabled
NotifyForm(3) = 00000100 = 4 ; retreat disabled
NotifyForm(4) = 00001000 = 8 ; delete disabled
NotifyForm(5) = 00010000 = 16 ; remove disabled
NotifyForm(6) = 00100000 = 32 ; escape disabled

For Sesame 2.0:
NotifyForm(7) = 01000000 = 64 ; extend mode disabled

These, of course, are combined to disable multiple things at once. So if you have 24, that means that delete and remove are both disabled (8 + 16). If you have 35 than means that post, advance, and escape are disabled (1 + 2 + 32). Etc...

Well all this binary stuff got me thinking. Unlike most Basics, SBasic doesn't have any binary operators or functions - so I added the following for Sesame 2.0:

BAnd(one as int, two as int) as int
BOr(one as int, two as int) as int
BXOr(one as int, two as int) as int
BNot(one as int) as int
BShiftLeft(one as int, two as int) as int
BShiftRight(one as int, two as int) as int
