I don't think that there is a command that will do this.

help strfun shows the following functions, they are what you need

subinstr(s1,s2,s3,n) returns s1 where the first n occurrences in s1 of s2 have been replaced with s3. If n is missing (.), all occurrences are replaced.

subinword(s1,s2,s3,n) returns s1 where the first n occurrences in s1 of s2 as a word have been replaced with s3. A word is defined as a space-separated token; a token at the beginning or end of s also counts as being space-separated.

substr(s,n1,n2) returns the substring of s starting at n1 for a length of n2. If n1<0, the starting position is interpreted as distance from the end of the string. If n2 is missing (.), the remaining portion of the string is returned.

Greetings Stata list members,
I have been unsuccessful searching the archives for commands (which will not require programming) that will do the following:

1. Edit words within a string variable that contains several words
2. Display this string variable with each word abbreviated to one or two letters.

Can anyone suggest a method?




Best wishes,
Michael
