FP.EXE IDE cursor and character input issues in DOS
"Oliver" wrote a bug report at:

with the title: "#375 Free Pascal package of FreeDOS isn't installed properly" and the following issue:
The characters [, ] and \ cannot be entered in the FP.EXE IDE under FreeDOS. Cursor keys don't work either. As a workaround, as soon as a program is run inside the IDE with a readln; command, the problem is temporarily solved.
