Try
str(ScoreNoLoad) to convert the integer to a string.
// Load Score Numbers
For ScoreNoLoad = 1 to 9
LoadImage (10 + ScoreNoLoad, "/gfx/number_" + str(ScoreNoLoad) + ".bmp")
Next ScoreNoLoad
You could use
int(mystring$) to convert a string to an integer.
That is what I do for my race track data file.
The file is 256 lines of numbers, but read in as an array of strings then converted to numbers for processing, then back to strings for paths.
My track section images have file names with numbered appendages, and I construct the file name for the images the same way as above.
