A prg-file contains a start address (the two first bytes) and some data. Prg files can be imported as memory blocks using the prgFiles parameter when defining the segment:
// Importing prg files when defining segment
.segmentdef Misc1 [prgFiles="data/Music.prg, data/Charset2x2.prg"]
// Another way of producing the same result
.segment Misc2 []
*=$1000 // Here we have to place the block manually
.import c64 "data/Music.prg"
*=$2000 // Here we have to place the block manually
.import c64 "data/Charset2x2.prg"
Again, this can freely be combined with other ways of adding blocks to the segment.
