Another Question about ASN.1 about opengeode HOT 10 CLOSED

What do you mean exactly by "all the char"?

from opengeode.

Perhaps you mean the characters from international alphabet 5 - see the complete set of characters here: https://www.ibm.com/support/knowledgecenter/en/ssw_ibm_i_73/nls/rbagscharset01169.htm

In that case I suggest you use the IA5String built-in ASN.1 type, instead of PrintableString (which is not supported in Opengeode)

If I want to represent the complete set of characters,do I need to list all character ranges? like this:

char ::= PrintableString (FROM ("a".."z")|FROM ("A".."Z")|FROM("0".."9")|FROM("+".."?"))

to represent them

from opengeode.

As I said, you just need to use the IA5String type instead of PrintableString. It contains this character set already.

like this???

char ::=IA5String;

a char::="a";

from opengeode.

No, like this:

1. First you subtype IA5String to give it size limits:

    MyString ::= IA5String (SIZE (0..100))

2. Then if needed you can define constants of this type:

    a MyString ::= "Hello, world"

3. If you want to use it in the SDL model:

    dcl a MyString := 'Hello, world';

I do not want to represent a String.I just want to represent character type. Like this. Is it right?

Char ::= IA5String (SIZE (0..1))

 dcl a MyChar := "H";

from opengeode.

If it is one char you can use (SIZE (1))
And then dcl a MyChar := 'h'; (use single quotes for strings in SDL, not double quote - sorry I made the mistake in my previous answer)

OK，Thanks for your help again.
