Hi All,

Just to let you know my ressults (+ one tiny question :-):
I did a bit of investigation and narrowed the "invalid" characters group to
jus one the hex 1a. My code now looks quite small:

fpath = 'c:\\pytemp\\bafir550.edi'
fl = file(fpath, 'rb')
print 'Checking file %s' % fpath
x=0
for line in fl.readlines():
x=x+1
if "" in line:
print 'Not allowed chars at line %s --- %s' % (x,line),
print "The check finished on line %s which was %s" % (x,line)

The only proble is tha in the if clause there actually is the hex 1a
character. The code works when executed from idle but when I run it from
command line, I get:

File "c:\Apps\PTOOLS\payfiles\editest.py", line 7
if "
^
SyntaxError: EOL while scanning single-quoted string

Is there any workaround?

Thanks Tom
