PH55625: CM PROC LUA OPTIM.MASK() ENHANCE PROCESSING OF CERTAIN NUMERIC DATA TYPES

Obtain the fix for this APAR.

APAR status

• Closed as new function.

Error description

• Optim ODPP supports a variety of NUMERIC data types, for
  example:
  
  o SMALLINT/INTEGER,
  o LONG_LONG,
  o FLOAT/DOUBLE.
  
  However, when attempting to process a source value of one of the
  above data types one needs to use the only numeric data type
  supported by Lua, which is DOUBLE, and use
  optim.source.getcolumnvalue() or
  optim.source.getcolumnasdouble() to pull the value.
  While Optim will convert the DOUBLE to a respective FLDDEF data
  type, there is a chance of data precision loss.
  
  One could use optim.source.getcolumnasbytes() to obtain the
  original unaltered value of such numeric columns but this
  function returns a "string type" value and Optim will not allow
  for such to be used with numeric data types from a FLDDEF.
  
  Note that a DECIMAL_370 FLDDEF already requires that the native
  value of the column be acquired by using
  optim.source.getcolumnasbytes().

  This APAR enhances processing of certain numeric data types
  while using the optimmask() function with Column Map PROCEDUREs.
  

Problem conclusion

• Optim processing will be enhanced.
  A numeric column's value can now be obtained using the
  optim.source.getcolumnasbytes() CM PROC function and mapped
  to the respective FLDDEF referenced by an optimmask() ODPP
  provider request, as long as the length of the string of bytes
  matches the length of the specified FLDDEF data type.
  The affected data types are:
  o SMALLINT/INTEGER,
  o LONG_LONG,
  o FLOAT/DOUBLE.
  
  Note that a DECIMAL_370 FLDDEF already requires that the native
  value of the column be acquired by using
  optim.source.getcolumnasbytes().
