Hi! I have tested the update 0.0.10-RELEASE but when I try to use shows the following exception:

And if I get the previous version works

Hi! First Thanks for this library, is really useful!!

I found a problem with decodeLength function, in BcdPrefixer.js.
When "(this.nDigits + 1) / 2" is a float, the floor operation is not performed automatically, e.g.:
this.nDigits = 2 then,
this.nDigits + 1/ 2 = 1.5,

for (let i = 0; i < 1.5 ; i++)

1st iteration 0 < 1.5 --- true
2nd iteration 1 < 1.5 --- true, JS not make automatically the floor operation, unlike Java implementation, and the second iteration shouldn't be performed.

Thanks for your help!

Can I use the example without using babel?

Anyway to generate System Trace Audit Number (STAN)?

JPOS can do this:

String stan = ISOUtil.zeropad(Long.toString(SpaceUtil.nextLong(sp, "STAN") % 1000000L), 6);

Hi. Thanks for a great library.

How would I create a Sub Field Packager?

The JPOS library has the ability to create sub fields. Here is the XML from JPOS:

 <isofieldpackager
            id="127"
            length="999999"
            name="RESERVED PRIVATE USE"
            class="org.jpos.iso.IFA_LLLLLLBINARY"
            packager="org.jpos.iso.packager.GenericSubFieldPackager">
        <isofield
                id="0"
                length="0"
                name="PLACEHOLDER"
                class="org.jpos.iso.IF_CHAR"/>
        <isofield
                id="1"
                length="8"
                name="BITMAP"
                class="org.jpos.iso.IFB_BITMAP"/>
</isofieldpackager>

I am setting up the fields so:

var packager = new Packager();
packager.fld = [ new IFA_NUMERIC(4, "MESSAGE TYPE INDICATOR"), ...

Is there a simple way to add a new sub field packager to the array with fields defined inside that?

Many thanks!

please help me

debugger;
var jspos = require("jspos");
var packager = require("./MyPackager");
var msg = packager.GetPakager.createISOMsg();

msg.setMTI('0800');

 let unpackMsg = packager.GetPakager.createISOMsg();
 unpackMsg.unpack(jspos.ISOUtil.hex2byte(msgStr));
 console.log(jspos.ISOUtil.hexString(unpackMsg.pack()));
res.render('index', { title: 'wwwww' });

}
catch (exceptiopn) {
console.log(exceptiopn)
