[SIgnificatif]

Hi Dear All.
I'm looking to use sas functions ( not re) to find strings in a plain text.

the text is like this :

data have:
some text blabla, bla right home num8, left home num7 bla bla bla

data want:
the variables left home and right home have the respectives values of num8 nad num7

conditions :
1) the numbers allowed are 0-8
2) the separator between right home with num and the left home and num could be
a space
, ( comma)
.period
'and' word
3) blanks between string num and 0-8 numbers should be removed , sometimes the text could be like right home num 8 ( a space between num and 😎

if there is no right home with num0-8 or left home with num0-8 found write in the respective variables 'not found'.

Thanks for your response.
