CHAPTER 4 Macro Key Programming • • • • • Introduction Macro key overview Syntax Using SFED8248.
Chapter 4 Macro Key Programming 4.1 Introduction Our workstations are equipped with programmable function keys (macro keys) that greatly enhance the operator interface. Macros, which are far more powerful than batch files, automate the most commonly used input sequences. They extended their functional reach to within application programs. 4.2 Macro Key Review The complete macro function consists of the following elements: Macro keys (SF1 , SF2, ...
4.3 Syntax Macro definitions consist of ASCII characters or character codes for special characters (ALT, ENTER, SHIFT, F1, SF2, and so on). These codes are predefined, and SFED8248.COM will display them on the screen for you. They are easily recognizable, appearing between the square brackets, "[" and "]". For example: ALT is represented by [26] ENTER is represented by [33] In your macro script, you can enter ordinary text (ASCII characters) or the code(s) of the required special character(s).
For example: ALT-F1 is represented by [26][44][90] CRTL-C is represented by [28]C[90] SHIFT-B is represented by [27]B[90] ALT-X is represented by [26]X[90] or [26]x[90] ALT-F1 is represented by [26][44][90] SHIFT-X is represented by [27]X[90] SHIFT-F1 is represented by [27][44][90] CTRL-X is represented by [28]X[90] CTRL-F is represented by [28][44][90] CTRL-ALT-DEL is represented by [28][26][41][90] (reboot) CTRL-ALT-A is represented by [28][26]A[90] CTRL-SHIFT-1 is represented by [28][27]1[90] Another use
4.4 How to use SFED8248.COM First, boot your system under pure DOS mode (not DOS shell in windows) and copy all the files to your hard disk and/or make a backup disk. Then start the macro editor. You will have to specify either an existing macro script file or a new macro script file. Here we will create a new file by typing SFED8248 NEWKEY.TXT [ENTER]. The following screen will appear: Advantech Workstation Special Function Key Edit Program Rev.
4.5 Example We will explain all macro functions that you can find in the EXAMPLE.TXT We will explain all macro functions that you can find in the EXAMPLE.TXT macro script file. When typing SFED8248 EXAMPLE.TXT the following editor screen will appear: Advantech Workstation Special Function Key Edit Program Rev.
SF1 = CD\TOOL[33] SFED825 EXAMPLE.TXT[33] This macro changes to the TOOL directory, then starts up SFED8248.COM with EXAMPLE.TXT. SF2 = COPY C:\CONFIG.EMM C:\CONFlG.SYS [33] Y [33] [85] [79] The configuration information is changed by copying CONFIG.EMM to CONFIG.SYS. After a delay of 5 seconds, [85], the macro invokes macro function key SF10, [79], which was defined to reset the system. SF4 = C:\WP51\WP[33][86][27][4D][90]REPORT.
