MIDB (Text,Start_Char,Num_Char)


where,

  • is a text string containing the characters to be extracted,
  • is the starting position of the first character to be extracted, and
  • represents the number of characters to be displayed in bytes.
    • MIDB(), returns a specific number of characters from a text string starting at the position you specify.MIDB is intended for use with languages that use the double-byte character set (DBCS).

Description

MIDB (Text,Start_Char,Num_Char) e.g. MIDB("<#*>",1,2) displays <# as a result.

  • MIDB works with the languages that use 'Double Byte Character Set' (DBCS).
  • MIDB counts each double byte character as 2, when language is set to DBCS. Else it counts 1 byte per character.
  • If argument is directly entered in the command, it should be enclosed in double quotes (e.g. "Name").
  • should be > 1, else Calci displays #N/A error message.
  • If > 'length of text', Calci displays empty text ("").
  • If + > 'length of text', Calci displays the characters up to the end of text.
  • If is negative, Calci displays an #N/A error message.

Examples

ABC DEF
*123*123 
=MIDB(A1,1,5) : Displays 5 character string in cell A1 starting from 1st position. 
Displays ABC D as the output. Space character is also included.
=MIDB(A2,1,1) : Displays 1 character string in cell A3 starting from 1st position. 
Displays * as the output.

Need to give examples with characters/language supporting DBCS
