Compare First `N` Characters of Strings

In a Requirements Table block, create a requirement that checks if the strings "abc" and "abc" are equal.

y = strcmp("abc","abc")

This example shows a requirement that checks if the strings "abc" and "abc" are equal.

You can also compare and sort string with relational operators. Use == to determine two strings are equal.

"abc" == "abc"

This example shows a requirement that checks if the strings "abc" and "abc" are equal.

Use ~= to determine if two strings are not equal.

"abc" ~= "abcd"

This example shows a requirement that checks if the strings "abc" and "abcd" are not equal.
