In line problems

I use the same structure of InLine - TextDisplay - Label1 - RestOfTrial with the following code:
if not (c.GetAttrib("BlockList.Sample") MOD 31 )=0 then goto Label1 ' change 31 to suit
This means that the experiment will offer a rest break after trial 30, trial 61 etc.
It is important to use a number that leaves a remainder from the MOD function, or you can find a rest being enforced with one trial to go!
Clearly this is something that lots of us have had to create solutions for. Perhaps it is something that could be a feature of the ListObject in a future version of E-Prime.

> Dear E-Prime Experts,

> I have designed an experiment that has 196 trials, and I wanted to
> introduce a text page after trial 98 offering a rest period to the
> participant. My problem is twofold:
>
> 1)First of all I tried to get e-prime to keep track of what trial we
> are on by referncing the "Block" attribute. I did this as follows:
>
> Dim Trial
> Trial=c.GetAttrib ("Block")
>
> However, when running it, e-prime did not recognise block as an
> attribute. So I tried to create my own:
>
> Dim Trial as integer
> Trial = Trial + 1
>
> This also did not work.
>
> 2)Secondly, I placed the "rest" page in my trialproc timeline, and
> tried to get e-prime to access it via an 'inline' at the end of the
> timeline:
>
> If Trial = 98 then
> Rest.run
> 'referncing my textpage for the rest period Else fixation.run
> 'this last line is trying to get e-prime to revert to the beginning
> 'of the trialproc timeline if the trial is not 98. This
> doesn't work End if
>
> How do I get e-prime to keep track of the trial number, and how do I
> introduce a rest page if a certain trial number is satisfied?

> Yours in confusion!
