<,> and how to use both

I want to check that a number is greater than 10 and
less than 20.
Seems I can't use something like
If myArray[1] >10 and <20
or any variations I can think of.
Can't find anything like 'instring' apart from
'contains' which I don't think will work with numbers...

Hi bjb007,
Rev can only check one condition at a time so you have to:
...
if myArray[1] >10 AND myArray[1] <20 then
...

Oh hell, not another one.
Rev seems to specialize in unnecessarily long
and convoluted ways of doing things.
Perhaps we could go back to the old "dot"
notation of dBase c. 1990...
If --- .and. ----.
If only Rev had a #define function.....
If only.....

Apologies and thank you.
I was rather annoyed at the time....
Now I'm trying to figure out how to increment the
contents of an array element. Has, say 1 in it
and I want to add 1.
Sure I've seen it somewhere but can't find it.

Just 2 euro cents:
I avoid dot syntax as the devil would holy water...
I like the wordy variants
Not too many dots for me please.
All the best,
Malte

xTalks tend to be a bit verbose at times, but you have to remember the times when a one-liner can achieve what would take many lines of code in some other languages.
In this case, if 'between' is a common requirement, you can easily factor it out to a function:
Code: Select all
function isBetween pNum, pUpperLimit, pLowerLimit
return pNum > pLowerLimit AND pNum < pUpperLimit
end isBetween
so then you can use
if isBetween(myArray[1], 10, 20) then....
Best,
Mark
