unable to pass string to function

AdirZig — Fri, 09 Jun 2023 18:04:42 GMT

Hi,

I am trying to pass to string to function, but its no working.

could someone advise what I do wrong?

// function
C_SC_PC_func2 = Function( 
    {SheetName, selSRM}, 
    {}, 
);

//call function
C_SC_PC_func2( "string1", "string2" );

I am not seeing an issue. Below is your code, with a Show() function, that gives results that indicates the string variables are passed in.

// function
C_SC_PC_func2 = Function( {SheetName, selSRM},
	{};
	Show( sheetname, selsrm );
);

//call function
C_SC_PC_func2( "string1", "string2" );

sheetname = "string1";
selsrm = "string2";

@AdirZig - you want the comma, not the semicolon, to make a list of local variables in the function. (Your list was empty, and I often start my function definitions with an empty list too.)

// function
C_SC_PC_func2 = Function( {SheetName, selSRM},
	{i,j}, // use comma
	i=3;
	j=4;
	Show( sheetname, selsrm );
);

//call function
i = j = 0;
C_SC_PC_func2( "string1", "string2" );
show(i,j);

JMP looks at the function function to see if it has three arguments. If it does, and the second argument is a list, it is a list of local variables. If you use a semicolon (making two arguments to function), it becomes a statement in the function body that is evaluated and thrown away.
