strcatk

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.

Syntax

Sdst = strcatk(Ssrc1, Ssrc2)

Sdst strcatk Ssrc1, Ssrc2

Examples

Here is an example of the strcatk opcode. It uses the file strcatk.csd.

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
