/NAMES[(=option)]
  /NAMES=UPPER         (D)

  Controls whether the compiler translates  external names (program-id's,literal
  entry-names in CALL statements, external  data  items) to uppercase, lowercase
  or leaves it unchanged.

  AS_IS           Causes VSI COBOL not to  change  the case of literal
 entry-names
                  for CALL statements.  The AS_IS option has no effect on
                  other external datanames or program-id names.  VSI COBOL does
                  not support mixed-case of external data names or program-id
                  names. However, specifying the AS_IS option may be useful for
                  calling  non-Cobol routines. When AS_IS is specified, external
                  datanames and program-id's are treated as if UPPER has been
                  specified.

  LOWER           Causes VSI COBOL to force  all external names (program-id's,
                  literal entry-names in CALL statements, external  data  items)
                  to be lowercase.

  UPPER           Causes VSI COBOL to force  all external names (program-id's,
                  literal entry-names in CALL statements, external  data  items)
                  to be uppercase. This is the default.

  The default is /NAMES=UPPER.
