In Sage X3, we may come across various scenarios where you need to get sub-string from an existing string. We can derive sub-string from both the ends i.e. From the Left and from the right or start from a particular position of a given string.
This blog will help us to extract the leftmost sub-string from a given string i.e. We can derive a sub-string with particular number character from the left of the given string.
Sage X3 provides the below special function to achieve the same:
left$ (string,nb_char)
This function is used to extract a substring starting from the left-hand side first letter of an original string to the letter ending with the specified number of characters.
Where,
string -> Original string with the alphanumeric expression
nb_char -> Numerical integer expression for the length of a string to be extracted.
Let’s consider following example for Extraction of sub-string with 4 letters from left to better understand the working of left$ function.
Snippet:
Local Char YSTRING(50)
YSTRING = “JACKFRUIT”
Infbox left$(YSTRING, 4)
The above snippet of code will give output as “JACK“.
Hope this helps!
