# Description

# This program converts a Forth source file from the FSB format
# to a ZX Spectrum TAP file suitable for Abersoft Forth, after
# being fixed by the Afera library
# (http://programandala.net/en.program.afera.html) to accept
# 11264-byte RAM-disk files).
#
# For the 16-KiB RAM-disk files, as implemented by the
# correspondent Afera module, use <fsb2-abersoft16k.sh> (ZX
# Spectrum 128 only); for the original system (without Afera)
# use <fsb2-abersoft.sh>.

# Main

fsb2 $1

# Get the filenames:

basefilename=${1%.*}
blocksfile=$basefilename.fb
tapefile=$basefilename.tap

head --bytes=11264 $blocksfile > DISC

# The bin2code converter uses the host system filename in the
# TAP file header (there's no option to change it) and Abersoft
# Forth needs the file in the tape to be called "DISC".  That's
# why an intermediate file called "DISC" is used.

bin2code DISC $tapefile

rm -f DISC $blocksfile
