A question about translating the following snippet of FORTRAN 77 into
Mata:
DO 120 J=1,NCV
. . .
IF (SM) 100,120,100
100 SM=SM*B
. . .
120 CONTINUE
I currently have the following (perhaps-too-literal) translation:
for (j=1; j<=ncv; j++) {
. . .
if (!sm) goto L120
sm = sm * b
. . .
L120: }
But in an aside exploration of Mata's behavior with an analogous probe
function, it seems that when a -goto- sends control to the
continuation line
as above, it behaves like a -break- and not a -continue-. Is it that
I'm
misremembering things FORTRAN? (The algorithm is still a little
difficult to follow at the moment, so the intention isn't obvious
from the
context.)
Can someone with a more trustworthy memory clue me in, and recommend
one of
the following as the replacement--or maybe suggest something better
still?
A:
for (j=1; j<=ncv; j++) {
. . .
if (!sm) continue
sm = sm * b
. . .
}
B:
for (j=1; j<=ncv; j++) {
. . .
if (!sm) break
sm = sm * b
. . .
}
Why not just do
for(j=1; j<=ncv; j++) {
if(sm) {
sm = sm*b
...
...
}
}
