the -svmat- Stata command has an inconvenient interactivity feature,
which always requests a confirmation, e.g.:
. svmat R
number of observations will be reset to 9
Press any key to continue, or Break to abort
obs was 0, now 9
If -quietly- or -capture- is applied, the text is not displayed, but
there is still a -more- condition, which pauses the execution of the
.do/.ado file, even if the dataset is empty (cleared with -clear-)
immediately before -svmat-.
Can this behaviour be changed somehow?
Currently, the only work around I've found is the following:
quietly {
clear
set obs `=rowsof(R)'
generate junk=_n
svmat R
drop junk
}
Note that even if the number of observations is set to the number of
rows in R, it is not sufficient for some reason to avoid the
confirmation. There must be a variable in the dataset. Can somebody
advise a shorter piece of code?

Have you tried -set more off-?
clear *
set more off
quietly describe
assert r(N) == 0
assert r(k) == 0
matrix define M = J(4, 4, 0)
quietly svmat M
list
exit
gives:
. clear *
. set more off
. quietly describe
. assert r(N) == 0
. assert r(k) == 0
. matrix define M = J(4, 4, 0)
. quietly svmat M
. list
+-------------------+
| M1 M2 M3 M4 |
|-------------------|
1. | 0 0 0 0 |
2. | 0 0 0 0 |
3. | 0 0 0 0 |
4. | 0 0 0 0 |
+-------------------+
. exit
end of do-file
If you want -more- to be set on routinely, then you could write a wrapper
for -svmat- that toggles the more condition:
program define svmat3
version 8.2
local more_condition `c(more)'
set more off
quietly svmat `0'
set more `more_condition'
end
