I was learning string functions in Stata. After obtaining help using help string functions command, one thing that particularly caught my attention was the strcat(s1,s2​​​) function which according to the description doesn't exist.
This is what the help documentation says.
strcat(s1,s2​​​​​)
Domain s1: strings
Domain s2: strings
Range: strings
Description: There is no strcat()function. ...............
  • ​​Why would Stata include help for a function that doesn't exist because I believe there are many other instances of operations which Stata doesn't have a command or functions for? What exactly was the motivation behind this?
  • Do I also expect similar documentations for other Stata commands and functions because I am still a newbie in Stata?
Regards.
