strcatk — Concatenate strings (k-rate)
Concatenate two strings and store the result in a variable. strcatk does the concatenation both at initialization and performance time. It is allowed for any of the input arguments to be the same as the output variable.
Here is an example of the strcatk opcode. It uses the file strcatk.csd.
Example 875. Example of the strcatk opcode.

Its output should include lines like this:
1 + 1 = 2 1 + 1 + 1 = 3 1 + 1 + 1 + 1 = 4 1 + 1 + 1 + 1 + 1 = 5 1 + 1 + 1 + 1 + 1 + 1 = 6 1 + 1 + 1 + 1 + 1 + 1 + 1 = 7 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 8 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 9 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 10 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 11 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = 12
