A very minor query re the -inlist- function. I'm using Stata 7 with
executable and ado-files as of 11 June 2002. According to -[U] 16.3
Functions-, the maximum number of arguments to -inlist- is 255 (either all
reals or all strings). However, for some reason, -inlist- seems to fail for
me with 6 string arguments. I might type as follows:
. disp inlist("bonferroni","hochberg","simes","yekutieli","krieger","liu")
expression too long
r(130);
When I click on r(130), I get error diagnostics as follows:
[P] error . . . . . . . . . . . . . . . . . . . . . . . . Return code 130
expression too long;
too many SUMs;
In the first case, you specified an expression that is too long
for Stata to process -- the expression contains more than 255 pairs
of nested parentheses or more than 66 dyadic operators. Break
the expression into smaller parts. In the second case, the
expression contains more than five sum() functions. This
expression, too, will have to be broken into smaller parts.
I can't see how
-inlist("bonferroni","hochberg","simes","yekutieli","krieger","liu")-
violates any of the limits on nested parentheses or dyadic operators,
although I know how to break up the expression, eg
seems to work, at the price of making the expression a bit more
long-winded. Is this an unpublicised feature of -inlist-? And does it have
any consequences apart from making long -inlist- calls a bit longer?
Thanks in advance
Roger
