Navigation and Commands for the TCD Editor

Introduction

The TCD Editor attempts to marry the functionality and similarity of the VM/CMS Xeditor Window system with the MVS/TSO Editor, while at preserving the flexibility of the PC's graphical user interface functions, such as Cut/Paste, Menus, Pulldowns; and the usability of the mouse.

The drive for originally developing this Editor was to provide programmers familiar with XEDIT and TSO Edit an editing facility that could be used on any PC Platform, whether Windows, Solaris, Linux or OS/2, and thus extending their ability to use their acquired knowledge and text editting skills to these platforms. We will use the VM/CMS XEDIT as the primary editor model to emulate insofar as look and feel and command structure.

The product is written in JAVA using the SWING and NetREXX classes. In theory, it can be ported to any computing base that supports the JAVA Run Environment and SWING Graphical User Interface.





**Please note that this program is under development. We are improving this facility on an "as we go" basis, adding functionality as we need it. The full richness of the Xedit and TSO functions is not there yet (especially when run as an Applet). We plan to have all the important, relavent and useful features, as well as PROFILING, STATUS setting and MACROs in a future release. However, in the meantime, as each new function becomes available it's name and description will be listed below.**



The Display Setup

The Editor Window consists of 3 main panels: the Command Area, the Prefix Area and the TextEditing (or File) Area. It also has a Status Area and a Message Line.

Editting and I/O commands (such as SAVE, OPEN, CANCEL) may be issued from the Command Area.

The Prefix Area is the panel that has the line (or row) numbers. Special commands can also be issued from here.

The TextEditting or File Area is where the input file is layed out. Each line is separated by a line_end character that is invisible.

When the ARROW or PAGEUP/PAGEDOWN keys are used the display will be repositioned (scrolled up or down) so that the CURSOR Line remains at the halfway point on the screen, unless you are near to TOP or BOTTOM.

Immediately under the Command Area is the Message Line. This will show error and informational type messages that may be generated by your editting commands.

The bottom panel is a Status Area. This shows your editting coordinates in both rows and columns, and pixels, along with offset from the beginning of the file. The area will also show INSERT/OVERLAY modes and CAPS ON mode.

Movement among the panels is performed by using the HOME, ENTER, TAB+CTL and the Down key.

Keyboard Setup

To move from Command Area to TextEditing Area use the Down or the Page_Down keys, or the HOME key. To move back to the Command Area from the Text Editing use the ENTER key or the HOME key.

To move back and forth between the TextEditing Area and Prefix Area use the CTL+TAB combination keys.

To return to the Command Area from the Prefix Area use the HOME key.



Arrow Keys move you up, down, right and left incrementally.

Set Commands

SET commands are entered in the COMMAND AREA window of the display frame.  They
are used to set up the behaviour of the display environment and of other Commands,
such as LOCATE and CHANGE.



All SET commands must be preceded by the word SET.




  


 
 DISPLAYMODE  Changes screen scrolling behaviour.


 
 
   STAY            Keeps view at current line while issueing commands that may
                   propagate change through entire file.
                   Syntax:   SET STAY  ON|OFF
 
                   Default:  OFF
   
   TRACING         Developer's edit subroutines tracing faciltiy               
                   Syntax:   SET TRACING  ON|OFF
 
                   Default:  OFF
 
   ZONE            Sets column limits for other editing command, such as LOCATE            
                   and CHANGE.  This restricts editing application command to the
                   specified columns.
                   Syntax:   SET ZONE first_col last_col
 
                   Default:  1  *

 
 




Prefix Area Function

Prefix commands are entered in the PREFIX AREA window of the display frame.  They
may be entered with or without intervening ENTER key strokes.



The double prefix commands, such as CC (COPY), are called Block Type commands.  You would
place these on the begin and last lines, by overtyping the line number.  This will
indicate the block of rows upon which you want to perform an operation.




  
   
   Permitted combinations:   CC block with F, P, A, B
                             C        with F, P, A, B
                             MM block with F, P, A, B
                             M        with F, P, A, B
                             DD block
 
   
   C                Copy a single row.
   
   CC               Copy a block of rows.
   


 
 m  Move a single or block of lines.


 
   
   D                Delete a single row.
                    Multiple single deletes can be processed together.   
                    This command can be performed over multiple lines
                    simultaneously.
   
   R                Repeat this row on next line.
 
   DD               Delete a block of rows.
   
   F                Insert row following this line.
   
   P                Insert row prior to this line.
   
   A                Insert row after this line (same as F).
   
   B                Insert row before this line (same as P). 
   
   I                Open an Input row following this line.
   
   O                Create a single row of SPACE following this line.
                    This command can be performed over multiple lines
                    simultaneously.
   
   /                Marker (forward slash) for PASTE operation.
