The comment appears to be irrelevant and/or misleading, although maybe that is just
because I don't understand your terminology. You say you create a "series of bind
statements", but you don't seem to do anything of the sort. You actually open four
files instead.
varlines =[]
varlines = fibindjclvar.readlines()
You don't need to pre-initialise a variable to an empty list before reading
lines.
for line in fi: #write out all the lines in the first part of JCL
fo.write(line)
fo.write('\n')
varline = ''
The above variable name is not helpful. "varline" -- what does it represent? It's very
similar to "varlines" defined above, so much so that the first time I read it I thought
you had overridden the same variable. Can you think of a more descriptive name for this?
Also, again, there's no need to pre-initialise it.
for dbrm in filistofdbrms:
fo.write('\n')
for index in range(0,9):
Is this correct? You only care about the first nine lines of the fibindjclvar
file? What if it has fewer than nine lines? What if it has more?
By the way, it is normal to write that as range(9) rather than range(0, 9).
if varlines[index].find('member') > 0:
varline = varlines[index] + '('+ dbrm + ')' + ' -'
else:
varline = varlines[index]
fo.write(varline)
Since you never use the index except as a way of extracting a line from
varlines, perhaps this snippet will be better:
for dbrm in filistofdbrms:
fo.write('\n')
for line in varlines[:9]: # Process only the first 9 lines.
if line.find('member') > 0:
line += '('+ dbrm + ')' + ' -'
fo.write(line)
fo.close()
fi.close()
fibindjclvar.close()
filistofdbrms.close()
This bit is fine :-)
