Key Sequence for Tool Parameters

Use Key Sequences to pass arguments from µVision to external user programs. Key Sequences are combinations of aKey Code and a File Code. Key sequences can be used, for example, in the dialogsTools, SVCS, Options for Target — User, or from the command line. The following rules apply:

• Certain Key Codes have to be duplicated when used from the command line.
  To use the symbols $, #, %, @, ~, ^
  escape them with $$, ##, %%, @@, ~~, ^^.
• Enclose Key Sequences within quotes (" ") when using folder names that might contain special characters (space,~, or #).

Key Codes and File Codes are listed in the tables below:

Key CodeDescription%File name with extension, but without path specification (PROJECT1.UVPROJ)#File name with extention and complete path specification (C:\MYPROJECT\PROJECT1.UVPROJ)@File name without extension or path specification (PROJECT1)$Folder name of the file specified in the File Code (C:\MYPROJECT)!File name with extention and relative path specification to the current folder (SRC\TEST.C)~ ¹Line number of the current cursor position^ ¹Column number of the current cursor positionFile CodeDescription$DDevice name as selected from the Device Database.EEditor file name currently in focus.FDepending on the context, this File Code returns:

• The file selected in the window Project.
• The currently active editor file.
• The file that is currently translated by a build process.

HApplication HEX file name (PROJECT1.H86).KRoot folder of the development tool (C:\Keil).LLinker output file. Typically the executable file used for debugging (PROJECT1).$MCPU mask revision number.PCurrent project file name (PROJECT1.UVPROJ).$WExpands the path with the root folder of a multiple-project. Applies to

• SmartCard multiple-projects.
• *.ini files. Not usable in interactive mode.
