LEFTB returns the first character or characters in a text string, based on the number of bytes you specify. LEFTB is intended for use with languages that use the double-byte character set (DBCS).

LEFTB(Text, Number_bytes)

where,

  • Text is a text string containing characters to extract,
  • Number_bytes represents the number of characters to be extracted.

LEFTB() displays the characters from a text string, depending on specified number of bytes.

Description

LEFTB(Text, Number_bytes)

e.g. LEFTB("String",2) displays St as a result.

  • LEFTB counts 2 bytes per character when system is set to language supporting DBCS, else counts 1 byte per character.
  • LEFTB works with the languages that use 'Double Byte Character Set' (DBCS).
  • Text can be any string containing characters, numbers, symbols, blankspaces etc.
  • If argument Text is directly entered in the command, it should be enclosed in double quotes (e.g. "Name").
  • Argument Number_bytes indicates the number of byte characters to be displayed from a text string. Number_bytes should be >0.
  • If Number_bytes >'length of text', Calci displays the entire text.
  • If Number_bytes is omitted, Calci assumes it to be 1.

Examples

Consider the following examples as input to LEFTB() function.

<#!#>
JOHN SMITH
123*123 
=LEFTB(A1,4) : Displays first 4 characters in a string from cell A1. Displays <#!# as the output. 
=LEFTB(A2,5) : Displays first 5 characters in a string from cell A2. Displays JOHN  as the output. Space Character is also counted.
=LEFTB(A2) : Displays first character J in a string from cell A2 as the output.
=LEFTB(A3,4) : Displays first 4 characters in a string from cell A3. Displays 123* as the output.
=LEFTB("Good Morning",20) :Displays the full text string Good Morning as the output.

Need to give examples with characters/language supporting DBCS
