Edytor STL

STL program editor

Program edition in STL language is carried out in STL editor – see window below.

Edytor STL

Editor window is opened in the workspace of PC Need and follows the Windows^® standards as regards the change of size and location, and closing.
Editor operation is similar to the use of a simple notebook. Text is entered from the keyboard using syntax principles given in STL. Programming is made in STL text language. It is possible to delete, shift or copy a selection or the entire text.

Marking – made using a mouse or a keyboard Mark –SHIFT+arrow keys (simultaneously press SHIFT and selected arrow keys, according to the shifting direction) – mark the selected text.

Cut – mark the text to be cut and Cut it by simultaneously pressing Ctrl and X keys. The text cut will be stored in the clipboard.

Delete – mark the text to be deleted and perform Delete operation – “Del” key.

Paste – put the cursor where the beginning of the text to be pasted is to be located, perform “Paste” command – combination of “Ctrl” and “V” (simultaneous pressing of Ctrl and V keys). Upon completion of the operation the content of the system clipboard is inserted.

Transfer – consists in marking (Mark) of the selected text and cutting it (Cut Ctrl+X) followed by pasting at the required location (Paste Ctrl+V).

Copy – mark the text to be copied (see: Mark) and Copy it using the combination of Ctrl and C keys (simultaneous pressing of Ctrl and C keys).

Comments
In order to improve the legibility of the program being edited comments can be added to it.
Comment texts are not taken into account when the executive code is created.
A comment which starts with „// or” is valid to the end of the line. Such a comment can be started from the beginning of the line or from the point behind a written instruction.
Examples:
// This is a comment starting from the beginning of the line.
; This is also a comment starting from the beginning of the line.
A I1 ;This is a comment inserted behind an instruction.
In order to omit a greater number of lines during compilation the following comment can be used: /* text */ Such a type of comment must define the beginning and the end of the text which will not be included in the program code.
Example:
/* A I1
A I2
= Q1
*/
A I3
=Q2
The first three instructions will be omitted when compiling the program. The source code will be created starting from A I3 instruction.

STL Compilation

IInitially the bottom window is empty, and after running he compile command (F7) the compilation report is displayed. If the program is correct a message is displayed (see Fig. 1.) to provide information on completion of the program compilation, code size and percentage of relay memory occupied.
Should the program contain errors, the message will indicate the error type and location [row number, column number] – Fig. 2., including comment.
