strsub — Extract a substring
istart (optional, defaults to 0) -- start position in Ssrc, counting from 0. A negative value means the end of the string.
iend (optional, defaults to -1) -- end position in Ssrc, counting from 0. A negative value means the end of the string. If iend is less than istart, the output is reversed.
Here is an example of the strsub opcode. It uses the file strsub.csd.
