Command in line X too long

Using the bochs freedos I tried to open DOS programs & games by a command in autoexec.bat Every time it gives me an error saying:
"Command in line X too long"

where x is the number of the line where I put the name of the executable file.

I have the 1.5 firmware on my PSP. Please help, Dizzy can't wait to become the prince of yorkfolk again :)

x is a variable over 0,
u cant find out what it means. reread the readme and be accurate in what ur doing .)
