This is a follow up to a question I posted earlier on parsing xAPI statements. I got the parsing to work and now I'm using the code below to get statements from the ADL LRS and it pulls the first 50 records. Is there a way to specify more records? Thank you.

recordStores: [

allowFail: false
}
]
}
);
var container = document.getElementById('response');
tincan.getStatements({
'callback': function (err, result) {
container.innerHTML = (err !== null ? 'ERROR' : parseMyData(result));
}
});
parseMyData = function(result) {
var statements = result.statements;
var output = '';
var name,verb,activity;
for(var i=0;i<statements.length;i++){
// check the statement for a usable name value
// (priority = actor.name, actor.mbox, actor.account.name)
if(statements[i].actor.name != null && statements[i].actor.name != "") {
name = statements[i].actor.name
}else if(statements[i].actor.mbox != null && statements[i].actor.mbox != "") {
name = statements[i].actor.mbox
}else{
name = statements[i].actor.account.name
}
// check the statement for a usable verb value
// (priority = verb.display['en-US'], verb.id)
try{
verb = statements[i].verb.display['en-US'];
}catch(e){
verb = statements[i].verb.id;
}
// check the activity for a usable value
// (priority = definition.name['en-US'], id)
try{
activity = statements[i].target.definition.name['en-US'];
}catch(e){
activity = statements[i].target.id;
}
output += name + ' - ' +
verb + ' - ' +
activity +
'<br>'
}
return output;
}

Use the code below to request statements with a set limit per page. If you make a request without a limit parameter or a limit of 0, then the maxmimum number of statements allowed by the server will be returned in the first page (this is what you are already doing above).
tincan.getStatements({ params: { limit: 100 }, 'callback': function (err, result) { container.innerHTML = (err !== null ? 'ERROR' : parseMyData(result)); }See https://github.com/adlnet/xAPI-Spec/blob/master/xAPI.md#stmtapiget
To get additional pages of statements use the TinCanJS LRS moreStatements method: https://github.com/RusticiSoftware/TinCanJS/blob/master/src/LRS.js#L766
See http://rusticisoftware.github.io/TinCanJS/ for how to create the LRS object.
