RSL or Object RSL (R-Style Language) - problem-oriented, interpreted, proprietary programming language, developed by R-Style Softlab for use in their software products. RSL is macrolanguage. It is free distributed and available for download to everyone.
RSL Language was established in 1994. The first additions was appeared only in 1997, and it has added the ability to connect the C ++ modules and RSL language became the object-oriented. In 1998 was added a few standard classes in the language. In 2003 support for .NET Framework module has been added.
RSL Shell - development environment, which includes:
- Text editor.
- Interpreter / precompiler.
- Editor of console dialogs.
- Editor of Pervasive PSQL database structures.
- Editor of Visual RSL graphical reports.
- SDK is used to create plug-in modules using C DLM SDK language.
Sample of program of processing messages into the dialog box:
macro EvenMacro(dlg, cmd, id, key) /* Set the focus of the input on field Dat */ if (cmd == DLG_INIT) SetFocus (dlg, “Dat”) return CM_IGNORE; /* if button F3 was pressed */ elif (cmd == DLG_KEY) if (key == 317) dlg.Int = 500; dlg.Lab = “NewLabel”; dlg.Str = “It is new line”; UpdateFields (dlg); /*if button Enter was pressed */ elif ( (key == 13) and (id == 6 ) ) SetFocus (dlg, 0); return CM_IGNORE; end; /* if button Button was pressed */ elif (cmd == DLG_BUTTON) /* Exit to save */ if (trim (fldname (dlg, id)) == “~O~k”) return CM_SAVE; /*Quit without saving */ elif (trim (fldname (dlg, id)) == “~C~ancel”) return CM_CANCEL; end; end; /* Verify data entry */ if (cmd == DLG_REMFOCUS) if ( (id == 1) and (dlg.Int < 100) ) MsgBox (“The value must be greater than 100”); return CM_CANCEL; end; elif (cmd == DLG_SETFOCUS) message (“Focus installed”); elif (cmd == DLG_SAVE) if (dlg.Int < 100) SetFocus (dlg, 1); MsgBox (“Value must be |>100”)); return CM_CANCEL; end; elif (cmd == DLG_DESTROY) message (“Dialog is destroyed”); end; return CM_DEFAULT; end
|Type Name||Declaration keyword||Type Code||Accepted values|
|Integer||Integer||Vs INTEGER||-2147483648 To 2147483647|
|Float||Double||V_DOUBLE||15 significant decimal digits|
|Float long||DoubleL||V_DOUBLEL||15 significant decimal digits (analogue Double)|
|A string of characters||String||V_STRING|
|Logical value||Bool||V_BOOL||True, False|
|Date and time||DateTime||V_DTTM|
|Link to RSL procedure||ProcRef||V_PROC|
|Link to method of RSL object||MethodRef||V_R2M|
|BCD number with 4 characters after the point||Decimal||V_DECIMAL||28 significant digits (analogue Numeric)|
|BCD float. It is used for real values (sums of money, exchange rates, interest rates and so forth.)||Numeric||V_NUMERIC||28 significant digits|
|Type of monetary values||Money||V_MONEY||28 significant digits (analogue Numeric)|
|Long type of monetary values||MoneyL||V_MONEYL||28 significant digits (analogue Numeric)|
|The special value "zero value", or the "default value"||SpecVal||No special constants. Type code 26||OptVal or NullVal|
|The special value "Empty"||-----||V_UNDEF||Null|
- Lexemes of DoubleL type is synonymous with Double type;
- Lexemes of MoneyL is synonymous with Money;
- Lexemes of Decimal is synonymous with Numeric;
For the internal representation of variables such as the Money type is used Numeric type. These types used in earlier versions of an RSL, were left only for the compatibility of the source code on the RSL.
Object data types are divided on specialized objects and generalized objects (GenObject). Generalized objects are created either directly by calling RSL-class constructor, or by using a standard procedure GenObject, receiving name of RSL-class as a string parameter. Constructor and procedure GenObect returns a reference to the created object . Currently, specialized objects are outdated. Into new code, it is recommended to use a generalized objects implemented to replace the specialized objects.
|Type Name||Declaration keyword||Type Code||Type of similar generic object|
|Link to a specialized object "database file"||BtFileRef||V_FILE||TBfile|
|Link to a specialized object "structure in memory"||StrucRef||V_STRUC||TRecHandler|
|Link to a specialized object "array of values"||arrayRef||V_ARRAY||TArray|
|Link to specialized object "text file"||TxtFileRef||V_TXTFILE||No|
|Link to a specialized object "dBase File"||DbfFileRef||V_DBFFILE||No|
|Link to the generic object of RSL class||Object for any object type, or < name RSL class>||V_GENOBJ|
