LASTSTEP_OUTPUT -limited number of chars?

[teognost]

I have some steps for C# solution compilation.
I am capturing the result of these steps using LASTSTEP_OUTPUT macro and writing it into a log file:

Const ForAppending = 8
Dim file
Set file=vbld_FSO().OpenTextFile(strCurrProjLogFullPat h,ForAppending,TRUE)
file.Write(vbCrLf&"*****************************"& vbCrLf)
file.Write(Application.ExpandMacrosAndScript("%LAS TSTEP_OUTPUT%"))
file.Close

However-I noticed some solutions are producing a bigger output and in the log file i do not see all the output,it is truncated.
So should I assume LASTSTEP_OUTPUT is limited as number of chars?
In such a case-how can I capture completely the result of these steps ?
