Edited by: Shubhali Agarwal

• To access a value at a particular index from a string or an array.

GETVALBYINDEX is used to extract a value from the specified index of a list (array or string) and store the result in the specified destination variable.

• DO NOT USE in the root node.
• Use variables only if they have been previously declared.
• To extract a value from the n^th position from a list, provide the (n-1)^th index, as index begins from 0.

GETVALBYINDEX command is for node level operations. It can be used in any node as an instruction, except for the root node. It should not be used on the Arrows.

Let's take an example: GETVALBYINDEX '3' $src_list $index_val
Here, "$src_list" has been declared as an array of strings and is equal to = [“This”,”is,”a”,”sample”,”string”]
It will result in $index_val equals to “sample”
