Purpose
Function to extract substring from left
Syntax
LEFT(<expC> | <memofield>, <expN>)
See Also
AT(), ATNEXT(), INLIST(), OCCURS(), RAT(), RIGHT(), SET STRESCAPE, STR(), STREXTRACT(), STRTRAN(), STUFF(), SUBSTR()
Description
The LEFT() function extracts a substring from the left of the character expression <expC> or memo <memofield> of width <expN> characters wide. The LEFT() function can be used on character fields in index expressions to extract part of the field in the index key.
Example
? left("Christopher",5) Chris
