STANDARD LIBRARY
## GENERAL Functions
isNaN(var) // for compatibility with Javascript
parseInt(szText, iRadix)
parseFloat(szText);
isNum(cChar)
isAlpha(cChar)
noexpr(szString) // use with replace for no regular expression (i.e exact match)

## NUMBER Functions
number.toString(radix)

## STRING Functions
// Assume that functions requiring an index does not support negative indexes.
// Assume result is undefined when a negative index is passed.
// the only exception is the slice method which only support 1 positive or negative index or 2 positive indexes
string.charAt( iPos_0based )
string.charCodeAt( iPos_0based )
string.fromCharCode(iCharactercode0, iCharacterCode1)
string.indexOf( szSearch, [iStart] )
string.len()
string.replace( szSearch, szReplacement )
string.split( szSeparator)
string.slice( iStart_0based, [iEnd_0based] )
string.toLowerCase()
string.toUpperCase()


## Array function
array.join(szSeparator)


## TO BE IMPLEMENTED
## Binary string operations ( also works on normal strings )
getByte (szBinaryString, iPos);
setByte (szBinaryString, iPos, iValue);
compress ( szBinaryString , szAlgorithm);
uncompress ( szBinaryString , szAlgorithm);
base64enc ( szBinaryString );
base64dec ( szBase64String );


## MATH Functions
Math.abs( iNum );
Math.acos( iNum );
Math.asin( iNum );
Math.atan( iNum );
Math.atan2( iNumY, iNumX );
Math.ceil( iNum );
Math.cos( iNum );
Math.exp( iNum );
Math.floor( iNum );
Math.log( iNum );
Math.max( iNum1, iNum2, ..., iNumN );
Math.min( iNum1, iNum2, ..., iNumN );
Math.pow( iNum );
Math.random();
Math.round( iNum );
Math.sin( iNum );
Math.sqrt( iNum );
Math.tan( iNum );

## DATE object
date.getFullYear();
date.getMonth();
date.getDate();
date.getHours();

io.readbyte(hFile, iNumBytes);
io.readline(hFile);
io.seek(hFile, iPosition);
io.size(hFile);
io.writebyte(hFile, szData);


## OS Functions
os.getenv( szVarName );
os.exit( [iExitCode] );
os.execute( szCommand );
os.gettime( blUTC );
