st: long macro
Dear All
I was trying to create a macro that contained a long list of (icd10) codes that are stored in a temporary dataset. There are 290 obs and icdcode is str4 variable, so I reasoned that thereshould not be any problem storing this many characters in a macro. Intercooled stata has a limit of around 68000 characters in a macro, so I was surprised to find that the that the code works fine until "`codelist'" reaches 244 characters in length. After that it fails to grow in subsequent iterations.
My code looks like this:
<snip>
version 9
local i=1
local codelist
while `i'<= _N {
local codelist = "`codelist'" + " " + icd10code[`i']
local ++i
}
<snip>
What am I doing wrong?
Many thanks
