[REBOL] Sorting non-REBOL data
From: swhite:ci:bloomington:mn:us at: 1-Mar-2010 10:22
I have to create a text file of 49-byte records (lines) in a fixed format, to create
an interface between two systems. I build it in memory and it looks like the sample
below.
122998 720095 100109 00006000 3 ACH
123472 541099 100109 00050216 1 201
123473 541099 100109 00047164 1 201
123534 527401 100109 00000777 1 201
123593 527401 100109 00024206 1 201

123638 551670 100109 00352098 1 101
Before I write it to disk, I want to sort it on that first six-digit number in positions
1-6. I looked up the documentation of "sort" and thought that the "skip" option is used
for fixed-format lines, with the number after the data name being a number that indicates
the size of the line. So I coded:
sort/skip PYIMPORT-FILE 49
The script returns a message of "Invalid argument: 49."
Is it possible to sort a fixed-format text file of non-REBOL data?
Thank you.
