Bug Description

(This is an upstream Debian bug, but I can only report it through this channel as I'm running Ubuntu.)

Observed behaviour:

Using source program zxfn.bas:

10 DEF FN s(x)=x*x
20 PRINT FN s(2)

and invocation

zmakebas -n zxfn -o zxfn.tap zxfn.bas

generates the following binary:

    00000000: 1300 0000 7a78 666e 2020 2020 2020 1f00 ....zxfn ..
    00000010: 0080 1f00 8a21 00ff 000a 0a00 ce73 2878 .....!.......s(x
    00000020: 293d 782a 780d 0014 0d00 f5a8 7328 320e )=x*x.......s(2.
    00000030: 0000 0200 0029 0d24 .....).$

which when loaded into a ZX Spectrum (either real or emulated) gives the error

Q Parameter error, 20:1

Expected behaviour:

Source and process as above, except using updated zmakebas from
https://derekbolli.wordpress.com/2012/11/16/create-zx-spectrum-basic-program-tap-file-from-text-source-file-in-bbedit-using-zmakebas/

generates the following more correct binary:

    00000000: 1300 0000 7a78 666e 2020 2020 2020 2500 ....zxfn %.
    00000010: 0080 2500 8a27 00ff 000a 1000 ce73 2878 ..%..'.......s(x
    00000020: 0e00 0000 0000 293d 782a 780d 0014 0d00 ......)=x*x.....
    00000030: f5a8 7328 320e 0000 0200 0029 0d30 ..s(2......).0

which when run as above, produces the expected output:
