In the console window the cursor can be used to select (highlight) text on the screen.
Below is a table containing the special keystrokes available when working in the console window.
| Keystroke | Function Performed |
|---|---|
| ctrl/a | selects all text (both on and off screen) |
| ctrl/c | places selected text into the clipboard |
| ctrl/m | places contents of message history into the clipboard |
| ctrl/t | places contents of screen (including scroll buffers) into the clipboard |
The console handles command recall. The user can recall the last 100 previously entered commands by using the UP and DOWN arrow keys.
To perform the following example, open the console window by clicking
on the Console Window icon in the SPDEV toolbar. Inside the console
window, type:
| Example 2-4 Command recall in the Console Window |
|---|
print date$ <--- type this line in and press [Enter] 20010716 //<--result print date$(days(date$), 3) <--- type this line in and press [Enter] 16-JUL-2001 //<--result print date$(days(date$), 3) <--- press the UP arrow key print date$ <--- press the UP arrow key, then press [Enter] 20010716 //<--result |
2.2.3 Using the [Tab] Key Features
When in the Sheerpower console, the [Tab] key can be used to perform various operations that cut down the time it takes to debug program code. As you get familiar with Sheerpower and the Sheerpower language, you will find that the [Tab] key features can be very helpful.
In the console window, enter part of a command and then press the [Tab] key. Sheerpower will then supply the full name of the command. If the command is ambiguous, a selection menu of all valid choices will appear.
In the following example, Sheerpower completes "so" to form the command "sort".
Open the console window by clicking on the console window icon in the
SPDEV toolbar. At the flashing cursor in the console window, type in
the word "so". Press the [Tab] key and you
will see "so" completed to be the command
"sort".
| Example 2-5 Command Completion in the Console Window |
|---|
so[Tab] <--- your entry, press [Tab] sort <--- Sheerpower supplies |
Next, type the word "in", then press the [Tab] key. In this example, "in" is ambiguous, so Sheerpower provides a menu of choices:
| Example 2-6 Command Completion in the Console Window |
|---|
in[Tab] +--Choices---+
| include |
| inf |
| input |
+------------+
|
The [Tab] key can be used to correct misspelled commands in the console window. Just position the cursor on the misspelled word using the left and right arrow keys and press the [Tab] key. The word will be replaced with its correct spelling. In the example below, the misspelled command SET STRUCTRE is changed instantly to the correct command spelling when the [Tab] key is pressed.
To perform the following example, open the console window by clicking
on the Console Window icon in the SPDEV toolbar.
Inside the console window, type:
| Example 2-7 Spelling Correction in the Console Window |
|---|
set structre[Tab] //<-- press [Tab] set structure |
Another example is below:
prannt[Tab] //<-- press [Tab] print |
Spelling correction of statements will also work in SPDEV. However, the console window and SPDEV use different methods to perform command completion. Therefore, they will not always agree on which command or statement you are wanting to complete. The [Tab] key is also used in SPDEV to execute the spelling correction.
In order for spelling correction with the [Tab] key to work in SPDEV, you must be editing an .SPSRC or .SPINC Sheerpower source file.
Sheerpower uses abbreviations for a number of commands in the Console Window. The [Tab] key can be used with any of the specific abbreviations to expand the abbreviations. To use this feature, enter an abbreviation and then press the [Tab] key. The period '.' must be used after each abbreviation. If an abbreviation is typed incorrectly a beep will sound when the [Tab] is pressed. The current abbreviations that can be used are:
| e. | edit |
| ee. | end extract |
| es. | extract structure |
| ex. | exclude |
| fe. | for each |
| in. | include |
| l. | list |
| li. | line input |
| lm. | line input menu |
| ls. | line input screen |
| oc. | open # |
| os. | open structure |
| p. | |
| pa. | print at |
| pc. | print # |
| pe. | print _extracted |
| pu. | print using |
| ss. | set structure |
SPDEV also supports the use of abbreviations and expansions to speed up and simplify programming. See Section H.6.1.1, Expansions and Section H.6.1.2, Abbreviations for instructions on setting up these features.
[BUILD 'file_path\program_name']
|
| Example 2-8 BUILD Command in the Console Window - Full File Path |
|---|
build 'c:\sheerpower\samples\send_email.spsrc'
Building c:\sheerpower\samples\send_email.spsrc ...
Lines processed: 202 (20200/sec), code space used: 4KB
|
Use the BUILD command to compile/build a program in the Sheerpower Console. Any errors will be displayed in the console when you perform the BUILD command.
The BUILD command used in the console window defaults to the main Sheerpower folder c:\sheerpower. When building a program that stored outside the Sheerpower folder, the full file path (location) of the program must be specified.
RUN ['file_spec']
|
| Example 2-9 RUN Command |
|---|
run 'c:\sheerpower\samples\eval' c:\sheerpower\samples\eval.spsrc 15-MAY-2015 14:46 |
The RUN command is used to execute a program after it has been written inside SPDEV. This way you can remain inside the console window and run your program after you experiment with elements of your program.
The RUN command can be used on its own (without the file location specified):
The RUN command executes programs. RUN with no file specification runs the current program.
When Sheerpower executes the RUN command, Sheerpower displays a header with the program name, current date and time. Sheerpower then executes the program.
A file specification can be given with the RUN command. If a file specification is provided, Sheerpower searches for the file, loads it, and then runs it. If no file type is given, Sheerpower will use the default file type .SPSRC.
