A long time ago, using the first compiler of R:base, I was able to pass
a variable when I started a compiled application
Something like this:
Testapp.exe testvariable
The value 'testvariable' was stored in a variable and could be used in
the program.
I cannot find anything in the help files.
A similar command is described in the run-command, but I don't see how
I can use this in a compiled environment
Tony,
The ability to pass parameters to any R:BASE instance, Runtime, and
compiled application is possible using the "STARTUPPARAMSTRnnn" and
"StartupParamCount" parameters of the GETPROPERTY command.
STARTUPPARAMSTRnnn - Returns the startup parameter value by the number
specified, where "NNNN" in StartupParamStrNNNN is the a number from
0 to STARTUPPARAMCOUNT.
Notes:
. This parameter is used with STARTUPPARAMCOUNT
. If NNNN = 0 (GETPROPERTY APPLICATION StartupParamStr0 VarName),
then VarName will always contain the executable name with path
. If NNNN > STARTUPPARAMCOUNT then VarName will contain the text:
"-ERROR-"
-- Example to Display Parameters:
Desktop Shortcut Target contains:
C:\RBTI\CompApp_ABC.EXE "-v" "-boss"
CLEAR VAR vCount,vParamStr0,vParamStr1,vParamStr2
GETPROPERTY Application StartupParamCount vCount
GETPROPERTY Application StartupParamStr0 vParamStr0
GETPROPERTY Application StartupParamStr1 vParamStr1
GETPROPERTY Application StartupParamStr2 vParamStr2
SET VAR vMessage TEXT = NULL
SET VAR vMessage = +
('EXE NAME:' & .vParamStr0 + (CHAR(13)) ++
'PARAM 1 :' & .vParamStr1 + (CHAR(13)) ++
'PARAM 2 :' & .vParamStr2 + (CHAR(13)))
CLS
PAUSE 2 USING .vMessage CAPTION 'Results' ICON INFO +
BUTTON 'Press any key to continue ...' +
OPTION MESSAGE_FONT_NAME Tahoma +
|MESSAGE_FONT_COLOR NAVY +
|MESSAGE_FONT_SIZE 11 +
|THEMENAME Longhorn
RETURN
StartupParamCount - Returns the startup parameter count for the
executable.
Notes:
. This parameter is used with STARTUPPARAMSTRnnn
Example:
GETPROPERTY Application StartupParamCount vParamCount
The above examples and many other parameters are available within
the "Application" Category of R:Docs 9.5!
