Hi STATALIST,


I need to create b from a :


Code:
* Example generated by -dataex-. To install: ssc install dataex
clear
input str37 a str27 b
"CT Angio Head to Feet (First 12 mths)" "CT Angio  (First 12 mths)"  
"Specials^02_PAN_FeetFirstCAP (Adult)"  "Specials^02_PAN_CAP (Adult)"
"Chest_Abdomen-_Trauma_Head/First"      "Chest_Abdomen-_Trauma_"     
"Chest_Abdomen-Non_Head-First_Con"      "Chest_Abdomen-Non__Con"     
"Chest_Abdomen-Routine_Head_First"      "Chest_Abdomen-Routine_"     
"Chest_Abdomen-Single_Head_First"       "Chest_Abdomen-Single_"      
"ChestAbdomen-Oncology_Head_First"      "ChestAbdomen-Oncology_"     
"Feet First_Prone_Fluoro"               "_Prone_Fluoro"              
"Prone_Planning_Feet_First"             "Prone_Planning_"            
"_Supine_Feet_First/Fluoro"             "_Supine_/Fluoro"            
"_Supine_Feet_First Planning"           "_Supine_ Planning"          
"Head_First_Prone_Fluoro"               "_Prone_Fluoro"              
"Prone_Head_First  Planning"            "Prone_  Planning"           
"Head_First_Supine_Fluoro"              "_Supine_Fluoro"             
"Head_First_Supine_Planning"            "_Supine_Planning"           
end


That means I need to delete "head to feet", "feet to head", "feet first", "head first".
These could be anywhere in the text.
Space(s) or any characters (-, _ , /, ...) could be between feet and first (or between head and first)

I really appreciate any advice and help.

Regards,
