Thanks  to Zhiqiang Wang and Nick Cox for their comments and suggestions.

It is not clear to me either, but running the program without braces produced:

- forvalues j = 1 / 2 {
- forvalues k = 1 / $catvar`j'_totline {
invalid syntax
  di "`k'. ${catvar`j'vname"`k'}"
r(198);

Zhiqiang's suggestion does work when the braces are used:

- local testvar = ${catvar`j'_totline}
- forvalues k = 1 / `testvar' {
- di "`k'.  `testvar'"
1.  9
- }
- di "`k'.  `testvar'"
2.  9
<snip>
}
}
