Hello everyone, I have a variable which contains items such as:

1.  Symptoms, signs, and abnormal clinical and laboratory findings

2. Injury and poisoning

 

I only want to keep the character portion: 

Symptoms, signs, and abnormal clinical and laboratory findings

Injury and poisoning

 

Could someone please help me?

If you know that every value has that numeric prefix then just remove the first "word".

want=left(substrn(string,1+length(scan(string,1,' '))));

Otherwise you will have to work harder first to figure out if the string does have the prefix.

data have ;
  input string $CHAR80. ;
cards4;
1.  Symptoms, signs, and abnormal clinical and laboratory findings
2. Injury and poisoning
;;;;

data want ;
  set have;
  new_string = prxchange('s/^ *\d+\. +(.*)$/\1/',1,string);
run;

Use the COMPRESS function.

 

 

variable = compress(variable,,'d');

This method does not remove the . as well ?

I would find the first period and remove from there onwards using substring.

Compress may inadvertenly remove any other numeric/periods.

However, these were likely used to order the data so assuming you don't need that you'll be fine. 

 

x=findc(variable, '.');
want = substr(variable, x);
