* Purpose
* =======
*
* PXERBLA is an error handler for the ScaLAPACK routines. It is called
* by a ScaLAPACK routine if an input parameter has an invalid value.
* A message is printed. Installers may consider modifying this routine
* in order to call system-specific exception-handling facilities.
*
* Arguments
* =========
*
* ICTXT (global input) INTEGER
* The BLACS context handle, indicating the global context of
* the operation. The context itself is global.
*
* SRNAME (global input) CHARACTER*(*)
* The name of the routine which called PXERBLA.
*
* INFO (global input) INTEGER
* The position of the invalid parameter in the parameter list
* of the calling routine.
