Hi,

Just a thought re using both LabTalk and C. I think it's possible to put all LabTalk code in a c file by defining strings as the LabTalk functions/sections etc. Using '\' makes the code manageable eg 

void test()
{

string LTstring="loop(numloop,1,100) {data1_a[numloop]$="pete";};"

LTexecute(LTstring);

}


Deining LTstring as a static string enables it to be called by all functions in the c file.
I think (not sure) the way to enable all the LabTalk code to 'global' is to define a function that returns the LabTalk code as a string.

This to me seems really useful and will aid managing my code and evolving from LabTalk to C over time!

Does anyone have any comment or know of possible limitations/problems that may arise (length of string?).

(Origin 7.5 attaching C files to projects : even better!)

Cheers,

Pete

Hi Pete,

Another way to do this is to organize your code as shown below. The Origin C compiler ignores everthing inside the ifdef LABTALK block (assuming of course LABTALK is not defined), and then to run the LabTalk code, you can issue commands from script such as:
run.section(file_path_and_name_of_C_file, MySection1)

Of course this is much easier in version 7.5 like you mentioned - Origin C files, LabTalk (OGS) files, or any other files can be attached and saved with an Origin Project.

In 7.5, when you issue a run.section command such as
run.section(just_file_name, section_name)
Origin will first look for a file and section of that name in attached files and run that if found. If not found, it will then look in User Files area, and then in the Origin EXE path.

#include <origin.h>

void MyOCFunction()
{
	out_str("My OC Function\n");
}


#ifdef LABTALK
[MySection1]
	type -b MySection1;
[MySection2]
	type -b MySection2;
#endif LABTALK

Thanks Easwar,

I guess the 'recommended' way is better! Getting carried away here...

Cheers,

Pete
