Brian Karfunkel <[email protected]> reports, "I'm getting a weird error,
-r(9611)-, when I run my program." Brian quoted about 50 lines of code.
I beleive I have uncovered the problem. In Code Block 1, Brian has
the following
foreach var of varlist `model_varlist' {
...
if (...) {
local model_varlist "`model_varlist' ..."
}
}
To wit, Brian changes the contents of the macro controlling the
loop, `model_varlist', in the body of the loop.
That is not allowed. It is not allowed in any of the syntactical
variants of -foreach-, including -foreach ... of varlist-,
-foreach ... of local-, ..., or -foreach ... in-. It is not allowed
for speed-of-execution reasons.
One way to code what Michael wants to do is
local i = 1
local var : word `i' of `model_varlist'
while ("`var'"!="") {
...
if (...) {
local model_varlist "`model_varlist' ..."
}
local var : word `++i' of `model_varlist'
}
By the way, another way of coding
local var : word `++i' of `model_varlist'
is
local i = `i' + 1
local var : word `i' of `model_varlist'
