mqt.run: args doesn't like spaces

[IanHeywood]

Trying to pass the following TaQL string to stefcal via the args switch in mqt.run:

SCAN_NUMBER > 3 && SCAN_NUMBER < 7

but the process bails out because it just selects the SCAN_NUMBER part. I've tried enclosing quotes (single and double) and backslash-spaces. Parameters with spaces in the tdlconf file itself are interpreted fine.

Am I missing a trick or is this a bug?

Here's my filthy stopgap solution:

def pokeTDLconf(filename,param,value):
        lines = []
        f = open(filename,'r')
        line = f.readline()
        while line:
                lines.append(line.rstrip('\n'))
                line = f.readline()
        f.close()
        f = open(filename,'w')
        for line in lines:
                parts = line.replace(' ','').split('=')
                if parts[0] == param:
                        print >>f,parts[0]+' = '+value
                else:
                        print >>f,line
        f.close()
