Welcome Thomas,
there are two possibilities
print,strjoin([file,'1st_PC.tif'],'_')
print,file+'_1st_PC.tif'
It is better to use a single quote ' because the double quote is used to
format numbers to octal numbers "10 is 8.

Or, if you are in a loop...
For i = 0L, nResults-1 Do Begin
...doStuff...
outputfile = file + StrTrim(i,2) + '_PC.tif'
write_tiff, outputfile, computed_image,ORIENTATION=2
EndFor

or, if you want to use the output filename somewhere else,
outputfile = file + '_1st_PC.tif'
write_tiff, outputfile, computed_image,ORIENTATION=2
