Origin Ver. and Service Release (Select Help-->About Origin): 2015
Operating System: 7 64bit

In LT, the following script is possible:
string str$=Test;
double TestVar=1;
%(str$)Var+=4; // TestVar=5

Is it possible to do something similar in OC ?

Thanks

Have some variables defined and want to get one of them by its name?
int vrbs(const string& s)
{
    Tree t;
    t.PM25.nVal = 700;
    t.Population.nVal = 21150000;
    t.TimeZone.nVal = +8;
    
    TreeNode tn = t.GetNode(s);
    if(tn)
        return tn.nVal;
    
    return 0;
}

The variable can be an integer/double/string/vector...

One way to dynamically "create" scalar variables in C is to use vectors.

You would be dealing with integer indices in the vector rather than an alphanumeric name for each element, but it works and seems to be the suggested method when one searches on the subject of dynamic variable naming in those languages.

Hi,

Since OC follows the syntax from standard C Programming Language so the variable manipulation you have asked might not be supported by OC.

Regards!

Hi Sean,

thanks for your reply but this is not what I was trying to do.
I want to manipulate variables in OC, not LT.

Hi,

Can you try the OC script below:

void test_lt_var(string str)
{
	double dVal;
	string strVar = str + "Var";
	LT_get_var(strVar, &dVal);
	dVal += 4;
	LT_set_var(strVar, dVal);	
}


Then you can run the defined function as following:

double TestVar=1;
test_lt_var("Test");
TestVar=;


It simply calls some of LabTalk functions from OC.

Regards!

Sean
