comment Execute command stored in aux file
I understand, but I want to read from the first file then write to a second file on the same run.

comment Execute command stored in aux file
Ok, Thanks. I've given a small clarification in the OP for what it's worth. The main issue at present is reading a command from an aux file and executing it on the same run.

comment Execute command stored in aux file
Thanks but the \fromFile is really a replacement for writing out \writeVerse{A}{1}{F} etc. each time since due to other factors beyond the scope of the MWE the parameters will change for \writeVerse. So in reality you would not see \writeVerse{A}{1}{F} in there at all except in the aux files. This script gets called by an external OS script and might have to be run even up to a 1000 times before the layout would be satisfactory. But that's handled by the external script. This TeX file just need to be able to read an executable command from the first aux file and write to the second.

@egreg Did you mean the input file? I've created the input file by some other means (manually in this case), that's why I've given the contents thereof separately. The output file gets created by the tex script. Both exists with contents after the xelatex run, although the output is shorting the first two lines, due to the write command not executing.

@egreg Thanks, but I thought I circumvented that issue by using two files. A \jobname.yposIN.txt and a \jobname.yposOUT.txt. Did I miss something there?

comment Unwanted code present in file output
Great this seems to solve the problem. I was not aware of the @ convention. Thanks. The pdflastxpos code was removed for the MWE.

@JosephWright Thanks, but your solution produces {1}{F} {\writeVerse }{F} in the output file. Please see question for clarification.

comment pdfsavepos coordinates remains zero
I see, thanks. I have adapted the solution from somewhere else and misunderstood the usage of immediate in this context.

@DavidCarlisle I might be missing something, but I don't think the parallel actually syncs my texts properly.
