UNISEQ

Returns the character code corresponding to a specified character.

Synopsis

UNISEQ(char)

Arguments

char An expression that resolves to a single character. If char is a string, UNISEQ returns the value of the first character.

Description

The UNISEQ function takes a character and returns the corresponding Unicode numeric code. Its inverse, the CHAR function takes a numeric code and returns the corresponding character.

The Caché MVBasic UNISEQ function returns the numeric value for a single character. The corresponding ObjectScript $ASCII function can take a string of characters and return the numeric value for a specific character by specifying its position in the string.

Note:

UNISEQ and SEQ are functionally identical.

Examples

The following example uses the UNISEQ function to return the numeric code associated with the specified character:

PRINT UNISEQ('A');    ! Returns 65.
PRINT UNISEQ('a');    ! Returns 97.
PRINT UNISEQ('%');    ! Returns 37.
PRINT UNISEQ('>');    ! Returns 62.

The following example uses the UNISEQ function to return lowercase letter characters and associated numeric codes of the Russian alphabet. On a Unicode version of Caché it returns the Russian letters; on an 8-bit version of Caché it returns a -1 (indicating a null string) for each letter:

letter=1072
FOR x=1 TO 32
  glyph=CHAR(letter)
  PRINT UNISEQ(glyph),glyph
  letter=letter+1
NEXT
