More Generic Function Example

Construct Features Hits Function

Here is an example on how to use functions to simplify the syntax when typing in the commands for a Constructed Circle from two Auto Circles.

If you have two Auto Circles named CIR1 and CIR2 then you would have to use the syntax CIR1.HIT[1..CIR1.NUMHITS],CIR2.HIT[1..CIR2.NUMHITS] for the Constructed Circle.

With this Function example

ASSIGN/PAR_ALLHITS1=".HIT[1.."
ASSIGN/PAR_ALLHITS2=".NUMHITS]"
ASSIGN/ALLHITS=FUNCTION((IDA),(IDA)+PAR_ALLHITS1+(IDA)+PAR_ALLHITS2)

All you have to type in is ALLHITS("CIR1"),ALLHITS("CIR2")

Code example

ASSIGN/PAR_ALLHITS1=".HIT[1.."
ASSIGN/PAR_ALLHITS2=".NUMHITS]"
ASSIGN/ALLHITS=FUNCTION((IDA),(IDA)+PAR_ALLHITS1+(IDA)+PAR_ALLHITS2)

Thanks a lot, very nice idea !!!!!
I was told that the demon will use .HITS, long time ago... but still not be there

I don't understand HOW this code is working (specifically the "IDA" stuff) but I understand what it accomplishes and will definitely be using this! Thank you !!!

Here is more info from the PC-DMIS Help Center.

Generic Function Example
Link: https://docs.hexagonmi.com/pcdmis/2021.1/en/helpcenter/index.htm#t=mergedProjects%2Fcore%2F26_expression_topics%2FGeneric_Function_Example.htm&rhsearch=Generic%20Function&rhsyns=%20

ASSIGN/MYFUNC=FUNCTION((X,Y,Z),X*3+Y*2+Z)
Creates a user-defined function and assigns it to the variable MYFUNC. The function takes three parameters, X,Y, and Z.

X is multiplied by 3.

Y is multiplied by 2.

Z holds the passed value.

The total of X + Y + Z is what gets returned when values are passed into the function, as shown here:

ASSIGN/V1=MYFUNC(7,2,5)
This assigns V1 the value 30 by evaluating the parameters passed into the function MYFUNC(7,2,5). 7 is the parameter and is substituted where X occurs in the expression portion of the function definition. Thus, X*3 becomes 7*3, or 21.

2 is substituted where Y occurs. Thus Y*2 becomes 2*2, or 4.

5 is substituted where Z occurs.

The values are then all added together (21 + 4 + 5) and passed to V1.

Functions Creating Other Functions Example
Link: https://docs.hexagonmi.com/pcdmis/2021.1/en/helpcenter/index.htm#t=mergedProjects%2Fcore%2F26_expression_topics%2FFunctions_Creating_Other_Functions_Example.htm&rhsearch=Generic%20Function&rhsyns=%20

Functions can create other functions.

ASSIGN/COMPOSE=FUNCTION((F,G),FUNCTION((X),G(F(X))))
Assigns COMPOSE to be a function that takes two functions as parameters and creates a new function using the two functions.

ASSIGN/ADD2=FUNCTION((X),X+2)
Assigns ADD2 to be a function that adds two to the parameter passed in.

ASSIGN/ADD3=FUNCTION((X),X+3)
Assigns ADD3 to be a function that adds three to the parameter passed in.

ASSIGN/ADD5=COMPOSE(ADD2,ADD3)
Assigns ADD5 to be a function composed of the functions ADD2 and ADD3.

ASSIGN/V5=ADD5(3)
Assigns V5 to have the value V8.

Your welcome. The "IDA" is the parameter name. The Generic Function Example from the Help Center in post #5 the MYFUNC uses three parameters X,Y,Z. You can name these parameters to your liking within the PC-DMIS naming rules.

Woah ! Mind blown. Never thought to use a function like that.

Just curious, why not put it all in one line like this?:
ASSIGN/ALLHITS=FUNCTION((IDA),(IDA)+".HIT[1.."+(IDA)+".NUMHITS]")

Is there an advantage to use variables for the ".HIT[1.." and ".NUMHITS]" strings?
