Dear friends and experts
In my project I use a (minor) modification of Ian Proudfoot's find/replace script.
The find- and replace-strings are taken from global arrays (which are filled from an RTF file).
Randomly the first call of the function FindAndReplaceString does not find/replace the item in question.
A trace of the function calls gives these results (first few items only):
~~~~ReplaceInDoc
~~~~~~FindAndReplaceString
find = >{Bartels, 1981 #14}< replace = >[1]<
~~~~~~FindAndReplaceString
find = >{Daube, 1989 #6}< replace = >[2]<
success
~~~~~~FindAndReplaceString
find = >{Daube, 2005 #15}< replace = >[3]<
success
Since the whole script is far to long for a justification of the problem, I have set up a testprogram which defines the findreplce stings directly (the test file is here😞
/* use test file t-find-replace.fm
There must be a subtle differene to the real script environment:
This test exhanges all occurrances
In FM-bilbio.jsx only the secont-to-last item is found and replaced.

var doc = app.ActiveDoc;
var flow = doc.MainFlowInDoc; // collection would have been failed, if flow/frame invalid
var inString = ["{Daube, 2005 #15}", "{Müller, 1925 #13}", "{SèsÃüs, #26}"];
var outString = ["[15]", "[19]", "[23]"];
for (j = 0; j < 3; j += 1) {
FindAndReplaceString (doc, inString, outString, 100);
}
function FindAndReplaceString (activeDoc, findString, replaceString, loopMax) {
// FindText, ConsiderCase; Function returns replacemtCounter
// Since we have collected only in doc.MainFlowInDoc, we replace only in this flow
// loopMax used as emrgency back door - twice the # of initially found citations
// We do not have an initial TextSelection, hence start directly at the first para

And guess what?
- opening the test-doc and running script => First item not found/replaced
- opening the test-doc and running script => OK (all 3 items found/replaced)
- opening the test-doc and running script => OK
- opening the test-doc, efresh script in catalogue, run script => OK
- opening the test-doc and running script => OK
- opening the test-doc and running script => OK
- After 3h of testing I'm tired now
I have not the slightest idea what may cause the random behaviour. Do You have any (the highest temparature sensed on the main board is 50°C (122°F) - not that alarming).
