I'm trying to rearrange the database below. I am looking for a command that extracts each number in "010,011,020" sequence and expands each one of them by row.

So I have
Code:
input str143 ind1990 str68 industry_bls str74 industry_bea
"010,011"                                 "Crop & Animal Production (Farms)"                 "Farms"                                          
"012,020,030,031,032"                     "Forestry, Fishing, and Related Activities"        "Forestry, fishing, and related activities"
And I would like to get:
Code:
input str143 ind1990 str68 industry_bls str74 industry_bea
"010"                     "Crop & Animal Production (Farms)"                 "Farms"
"011"                     "Crop & Animal Production (Farms)"                 "Farms"                                                    
"012"                     "Forestry, Fishing, and Related Activities"        "Forestry, fishing, and related activities"
"020"                     "Forestry, Fishing, and Related Activities"        "Forestry, fishing, and related activities"      
"030"                     "Forestry, Fishing, and Related Activities"        "Forestry, fishing, and related activities"      
"031"                     "Forestry, Fishing, and Related Activities"        "Forestry, fishing, and related activities"      
"032"                     "Forestry, Fishing, and Related Activities"        "Forestry, fishing, and related activities"
Is there a command for that?
