Local fix

• WTXCQ - WTX00031793
  LV / LV
  Circumvention:
  
  Override -IE5 is in error. Needs quotes.
  

Problem summary

• Users Affected:
  WebSphere Transformation Extender users invoking maps with empty
  echo override command
  
  Problem Description:
  Core dump in ParseArgs when passed empty echo parameter .  For
  example (-IE2   -IE3 data).
  
  Platforms Affected:
  All
  

Problem conclusion

• Empty echo parameter, for example (-IE2   -IE3 data) is not
  allowed and a syntax error. Echo parameter must contain data
  other than spaces or be enclosed by quotes.
  The invalid echo parameter will now be detected, flagged as
  command line error thus preventing the exception.
