ascii_val

Library: ib_udf

Added in: IB

Better alternative: Internal function ASCII_VAL()

Description

Returns the ASCII code of the character passed in.

Result type: INTEGER

Syntax 

ascii_val (ch)

Declaration 

DECLARE EXTERNAL FUNCTION ascii_val
  CHAR(1)
  RETURNS INTEGER BY VALUE
  ENTRY_POINT 'IB_UDF_ascii_val' MODULE_NAME 'ib_udf'

Caution: Because CHAR fields are padded with spaces, an empty string argument will be seen as a space, and yield a result of 32. The internal function ASCII_VAL returns 0 in this case.
