Synopsis
LEFT(string,length)
Arguments
string An expression that resolves to a string from which the leftmost characters are returned.
length An expression that resolves to a positive integer indicating how many characters to return. If 0, a zero-length string ("") is returned. Fractional numbers are truncated to an integer. If greater than or equal to the number of characters in string, the entire string is returned. No padding is performed.
Description
The LEFT function returns the specified number of characters from the beginning (left end) of a string. If you specify a length greater than the string length, the entire string is returned. To determine the number of characters in string, use the LEN function.
The RIGHT function returns the specified number of characters from the end (right end) of a string.
Examples
The following example uses the LEFT function to return the first three characters of MyString:
MyString = "InterSystems"
PRINT LEFT(MyString,3);   ! Returns "Int"
