How to use JSL how to modify decimal numbers to binary data in this format?

Thanks!

This is just a conversion to Hex

Names Default To Here( 1 );
a = "000903";
theHex = "";
i = 1;
While( Substr( a, i, 1 ) != "",
	theHex = theHex || Hex( Substr( a, i, 1 ) );
	i++;
);
Show( theHex );

This returns

theHex = "303030393033";

Thank Jim!

So I understand the principle of calculation.But I still can't figure out how to end up adding something else and saving it in this format.

Thanks Experts!

c = "0000000000000000000000000000000000";

34——OK

c = "0000000000000000000000";

22——wrong

I don't understand 34=OK and 33=wrong

That's what's right. C has to have 34 zeros.

d="0100303030393033000000000000000000000000000000000001003939393939390000000000000000000000000000000000"

@lala , it's really hard to follow you, what you do and what you want. I think the suggestion of Jim is fine, and your problem is not in JSL but in file operations.

My feeling is that you shouldn't write binary data in a text file. If this would work, you should be able to re-read it, but this is not the case, JMP throws an errror.

Names Default To Here( 1 );

tem = {"000903", "999999"};
b = "0100";
c = "0000000000000000000000000000000000";
d = "";
j = 1;
For( j = 1, j <= N Items( tem ), j++,
	a = tem[j];
	theHex = "";
	i = 1;
	While( Substr( a, i, 1 ) != "",
		theHex = theHex || Hex( Substr( a, i, 1 ) );
		i++;
		
	);
	d = d || b || theHex || c;
);
Show( d );
Show( "d = 0100303030393033000000000000000000000000000000000001003939393939390000000000000000000000000000000000" );
filename = Save Text File( "TEMP\try1.dat", Hex To Blob( d ) );
text = Load Text File( filename );
Show( (Blob To Char( text )) );

Sorry, I've been wrong, Load/Save Text File supports BLOB, see scripting index. But I think anything else is going wrong during file operation. Below JSL with option for reading BLOB.

Names Default To Here( 1 );

tem = {"000903", "999999"};
b = "0100";
c = "0000000000000000000000000000000000";
d = "";
j = 1;
For( j = 1, j <= N Items( tem ), j++,
	a = tem[j];
	theHex = "";
	i = 1;
	While( Substr( a, i, 1 ) != "",
		theHex = theHex || Hex( Substr( a, i, 1 ) );
		i++;
		
	);
	d = d || b || theHex || c;
);
Show( d );
Show( "d = 0100303030393033000000000000000000000000000000000001003939393939390000000000000000000000000000000000" );
filename = Save Text File( "$TEMP\try1.dat", Hex To Blob( d ) );
text = Load Text File( filename, BLOB );
Show( (Blob To Char( text )) );
