BEG AT / END AT Statements

Overview

• RAW operand:
  • No change from the current behavior.
• Group operand:
  • No change from the current behavior.
• UNICODE or NATIONAL operand:
  • No change from the current behavior.
  • Must allow for length to be longer.
• Literal operand:
  • All literal values are considered to be RAW alpha values and encoding of 8859-15.
  • Unicode escape sequences are NOT honored.
  • Literal values are entered as a string of single-byte characters with an 8859-15 (RAW Alpha) encoding. The string of bytes representing the literal characters is later used as a constraint for the key specified on a corresponding BEG READ or READNEXT statement. No conversion or transcoding of a literal BEG AT/END AT value is performed regardless of the type of key field specified on the corresponding BEG READ/READNEXT statement. This means that literal values on a BEG AT/END AT statement should probably only be used when the key field on the corresponding BEG READ/READNEXT statement is a RAW alpha field.

Test Plan

• Test with Raw operands
• Test with Group operands
• Test with UNICODE and NATIONAL operands
• Test literal operands with Raw keys
• Test literal operands with National/Unicode keys (should be error)

Bugs

1. Errors not not thrown when literals are used with Unicode/National keys * Not a bug * Functions as designed.
2. Records not read when using a group field that includes Unicode characters. * Fixed * Tested May 23 engine
