[amibroker] Re: File Reading/Writing

["acesheet" <acesheet@xxxxxxxxx>]

Thanks for the help everyone. I ended up using fputs(), etc. and 
#include in one script to write the following to a file. The 
following code sets up a reference file.

//---------------------------------------
p1=Param("1) S/T Period",20,3,373,1);
p2=Param("2) I/T Period",50,3,373,1);
p3=Param("3) L/T Period",144,3,373,1);
periods="p1="+NumToStr( p1, 3.0, False)+";"+"p2="+NumToStr( p2, 3.0, 
False)+";"+"p3="+NumToStr( p3, 3.0, False)+";";
fileperiods=fopen("Periods.txt","w");
if(fileperiods)
{
fputs( periods, fileperiods ); 
fclose( fileperiods ); 
}
//---------------------------------------

The contents of the file 'Periods.txt' after being set with 
the 'param' commands above:

p1= 24;p2= 35;p3= 85;

Then I simply use the #include command to link all the other charts 
that I want to use these periods with.

Thanks for the help.
