few functions

1. max()
2. Read the documentation (cdnshelp in current versions or cdsdoc in IC5141), or use cdsFinder as a quick starting point 
3. This is a pretty pointless question. I cannot see how it can be helpful to pick out a few random functions which happened to get used a lot. For example, I could say if(), let(), procedure(), list(), cons(), dbOpenCellViewByType() - but would that teach you anything?

Thanks for help andrew.

I will start with understanding  of commonly used functions (using cdsFinder and google) for learning basic scripts and then moving to complex scripts and actively contributing to this forum.

Thanks again to this forum.

I find listFunctions() combined with help() to be very effective for discovering functions I've never used before (or forgotten about) that might be relevant to the problem at hand.

Mathematically, the most important SKILL functions are the ones given in McCarthy's paper (commentary here). Those seven (plus lambda()) make up the core of any Lisp system, and are sufficient to program any computable function.

Amaze your friends by writing a SKILL evaluator for SKILL in one page of code!

It worked for the interger.For List I used as below:

I used below logic to get minimum x coordinate  in the list :

e=car(templx) 

foreach(a templx

if(e>a e=a)))

Is there more effective way of doing this?

Thanks

A more succinct way of doing the above is:

apply('min mapcar('car templx))

The mapcar function is transforming the list of points to a list of the car of each point, and then this list is being passed as the arguments to the min function.

 Hi Andrew,

I tried above suggestions :

I am getting below error:

*Error* car: argument #1 should be a list (type template = "l") - 1

for simple testing I made templx=(1,2,3,4) and then mapcar

mapcar('car templx)

 is giving above error.

just out of curisity:

Is there way to mark the query as solved in this forum ?

Use:

 templx=list(1,2,3,4) 

or

  templx='(1,2,3,4) 

sorry for the typo

I used templx=list(1,2,3,4) in above case and got error.

Sorry, I misread the question (in my defence, it was ambiguous, because it was talking about finding the minimum x coordinate in the list, so I assumed that what was being last was a list of coordinates (a coordinate is usually represented as a two-element list)).

If it's just a simple list:

templx='(2 3 1 5 7)

you can just do:

apply('min templx)

Note you don't need to add commas between list items when defining a list. It's tolerated, but I don't believe it's documented...

Andrew.
