doFork

protected void doFork(Polyad polyad,
                      State state)

Run a script in its own thread. Passed variables are shared.

Parameters:: polyad -; state -

doInterrupt

protected void doInterrupt(Polyad polyad,
                           State state)

getMyLogLevel

protected int getMyLogLevel(Level level)

doModulePaths

protected void doModulePaths(Polyad polyad,
                             State state)

doScriptPaths

                            State state)
```
This will return a given script arg for a given index. No arg returns then number of arguments;

Parameters:

polyad -

state -

doScriptArgs2

protected void doScriptArgs2(Polyad polyad,
                             State state)

New function for script arguments. Better contract.

Fixes github issue 3.

Parameters:: polyad -; state -

doOSEnv

protected void doOSEnv(Polyad polyad,
                       State state)

doSysInfo

protected void doSysInfo(Polyad polyad,
                         State state)

runScript

protected void runScript(Polyad polyad,
                         State state)

Run an external qdl script with its own state. Ouput goes to the current console.

Parameters:: polyad -; state -

loadScript

protected void loadScript(Polyad polyad,
                          State state)

resolveScript
```
public static QDLScript resolveScript(String name,
                                      List<String> paths,
                                      State state)
                               throws Throwable
```
This will use the path information and try to resolve the script based on that. Contract is
1. name start with a # ==> this is a file. If server mode, fail. if abs, do it, if rel resolve against file path
2. name is scheme qualified: if absolute, just get it, if relative, resolve against same scheme
3. no qualification: if absolute path and server mode, fail, if relative, try against each path
NOTE: First resolution wins.
NOTE: If this returns a null, then there is no such script anywhere.
Parameters:

name -

state -

Returns:

Throws:

Throwable

```
The general contract for import. You may import everything in a module by using the uri. You may import items using the FQ name (uri + # + name).

Imported items are added to the current stack only. it is not possible to un-import items since it is impossible to track down references to them and it is dangerous to have programs be able to unload things willy-nilly since that can cause hard to track down failures.

If you need to unload, your best bet is to clear the workspace.

Parameters:

polyad -

doInterpret

protected void doInterpret(Polyad polyad,
                           State state)

doSay

protected void doSay(Polyad polyad,
                     State state,
                     boolean printIt)

Does print, say and to_string commands.

Parameters:: polyad -; state -; printIt -

doVarType

public void doVarType(Polyad polyad,
                      State state)

Get the type of the argument.

Parameters:: polyad -; state -
