/**
  @file
  @brief Update the source code of a type 2 STP
  @details Uploads the contents of a text file or fileref to an existing type 2
    STP.  A type 2 STP has its source code saved in metadata.
 
  Usage:
 
      %mm_updatestpsourcecode(stp=/my/metadata/path/mystpname
        ,stpcode="/file/system/source.sas")
 
  @param [in] stp= the BIP Tree folder path plus Stored Process Name
  @param [in] stpcode= () The source file (or fileref) containing the SAS
    code to load into the stp.
    For multiple files, they should simply be concatenated first.
  @param [in] minify= (NO) Set to YES in order to strip comments, blank lines,
    and CRLFs.
  @param [in] mDebug= set to 1 to show debug messages in the log
 
  @version 9.3
