eXpress Script Editor (BasicScript, PascalScript, JScript)

What it is

The eXpress Script Editor is the authoring environment for scripts that drive the eXpress family. It supports three languages — BasicScript, PascalScript, and JScript — plus a debugger, a Tools menu (Check Script F4, Compile F5, Mass Compiler, Dialog Designer), and a configurable editor (font, tab stops, syntax highlight colors).

Choosing a language

• BasicScript — Sub Main / End Sub structure, Dim / End Type, If/ElseIf, Do/Loop, For/Next, With
• PascalScript — begin/end blocks, Procedure/Function with typed parameters, Const, Case, While/Repeat
• JScript — function blocks, var declarations, for/while/switch, true C-family syntax

Sub Main
  Dim x As Integer
  For x = 1 To 10
    If x Mod 2 = 0 Then ShowMessage(IntToStr(x))
  Next x
End Sub

Common elements across all three languages

• Variables, array index referencing, and variable scope rules
• Uses / Imports directives to bring in eXpress scripting classes
• Built-in conversion, formatting, date/time, and string-handling functions
• Wait(milliseconds), ShowMessage(string), and other shared procedures

eXpress scripting classes

Scripts have access to a set of eXpress-specific classes for clipboard handling, printing (BeginDoc/EndDoc), dialog forms (LoadForm, ShowForm, mrOk/mrCancel result codes), and component event hooks. The Dialog Designer (F10) builds forms visually and emits the matching object references your script can manipulate.

var df : TDialogForm;
    rslt : Integer;
begin
  df := TDialogForm.Create;
  if df.LoadForm('myform.frm') then begin
    rslt := df.ShowForm;
    if rslt = mrOk then ShowMessage('Saved');
  end;
end.

Common dialog classes

• TOpenDialog / TSaveDialog — file selection
• TPrintDialog / TPrintSetupDialog — printer selection and setup
• TFontDialog / TColorDialog — visual pickers reused across forms
