The function, subinstr(), (or regular expression functions) will do it.
E.g., gen newvar = subinstr(oldvar,"dis","reg",.).

Subject: st: Replace a substring

Hi,
I am hoping that this is quick and simple to answer. I want to replace 
all occurrences of a substring in some string variable with another 
substring. E.g. I want to replace "dis" with "reg" so that the old 
variable has the values:

oldvar
dis14
batidis
leg_diszone
cont

and the new variable is

newvar
reg14
batireg
leg_regzone
cont

Using Nick's egenmore, this can be done for whole words using -msub-, 
but how can this be done when the string to be replaced is not a whole 
word?

Thanks,
tewodaj
