The input text string has length of 200 must be broken down into text blocks of 40 characters . Each break of text must not be done in the middle of a word. If the last word does not fit into the end of the 40 character string, that word must be cut and then pasted into the start of the next 40 character string.
Total number of 40 character strings are to be calculated and sent to the output.
Each 40 character string must have a corresponding row number sent to the output.
Can you please tell me how to do it UNSTRING command |

Hi,
Did somebody challenged you to do it using unstring!! 
If not you can do it using reference modification.

| Look at the 40th byte. If it is a space, move all 40 bytes. If it is not a space, go backwards to find the last space before the 40th byte. Move bytes 1 through wherever the space is, then start again from the character after the space. |
