The 1.0.0 version only allowed for 16 character long file paths, which made sense when the only drive system available for the F256 was a 1571, 1541, etc., but now that the kernel has supported SD cards for a long while, you may have your CBM BASIC files in a subdirectory. This version lets you type "c128_basic_progs/MYPROGRAM", etc.
This version is the first available as a pgZ. From f/manager, select "basic2text.pgz" and hit ENTER. From DOS, type "- basic2text.pgz". From SuperBASIC, type "- basic2text.pgz"
