Maximum length of a macro value?

[teognost]

Hi
I would like to store the content of a file in a Visual Build macro.
Is there any limit of how many chars can be stored?
I am thinking if there is a possibility the macro would contain just a part of the file content in case the text is very long.
The code is (in RunScript step):

strSVNChangesTxtFileInitialBranch=Application.Expa ndMacros("%SVN_CHANGES_TXT_FILE_INITIALBRANCH%")
Set scisc = vbld_AllMacros()("SVN_CHANGES_INITIALBRANCH_SPECIF IC_CHANGES")


Set FSO = CreateObject("Scripting.FileSystemObject")
Set oFile = FSO.OpenTextFile(strSVNChangesTxtFileInitialBranch )
scisc.Value = oFile.ReadAll
oFile.Close
