I said [3/4/2018] I wasn’t going to do much more to my greenbar program but I did add holes to the side of the listing. Here once again is a Before and After GnuCOBOLlisting. Here’s one in blue, I personally never saw this color at school or in our shop…however I know it exists. Not […]
Been learning Python’s XML handling. Very useful. I like how easy it is to get to nested tags that may or may not exist. I have been rewriting my Diaro (android diary app) file export [to XML format] processing program, to use this method. Why not use this tested [probably by thousands and maybe millions […]
Well I finally got around to timing My Julia rewrite of a Python program (see 11/13/2017). Wow…from noticabably slower 6 months (see my comments 9/18/2018) ago to much faster 19 min vs 1hr 15min. bill@billb-MS-7B79 ~/Mystuff/Julia $ ./runIt.sh Wed Mar 20 16:30:13 EDT 2019 Records to create 1000000 5000 Written 995000 […]
It seems GnuCOBOL’s supposed ASCII/EBCDIC builtin conversion doesn’t work. So I wrote my own. Verified EBCDIC output with my Julia ditto [named after the IBM utility] program.
GnuCOBOL has an option to create a xref listing. So I again modified my Python 3 greenbar program to do page breaks when it sees the form feed, because GnuCOBOL put them there. For non GnuCOBOL output files I count lines and manually goto a new page! Here is an example of a GnuCOBOL listing […]
Wrote control break GnuCOBOL program. Sort on State, City an do a control break on State printing totals at the break.
Add an random amount field [0.01-100.99] to my Julia program that generates real “looking” customer data. I did this so I could practice numeric calculations in GnuCOBOL. Wrote GnuCOBOL program that uses the COBOL SORT output to printer, with a heading and final total for a amount field in the input.
Modify my Python 2 greenbar program to Python 3, specifically to print GnuCOBOL programs or output, for that nostalgic IBM look. Here’s a very simple GnuCOBOL example.
Another more advanced GnuCOBOL program that uses the COBOL SORT. Pretty nice COBOL! Sort was so fast on my first test of 5000 records, that I reran on 50,000 records. Still literally ran in the blink of an eye. So I timed it. bill@billb-MS-7B79 ~/Mystuff/COBOL/progs $ time ./sort01 [GnuCOBOL program] real 0m0.107s user 0m0.064s sys […]
Decided to kick the tires of GnuCOBOL, pushing it a little harder. Wrote a little more advanced GnuCOBOL simple array program that Uses: REDEFINES, OCCURS, VARYING. I have previously wrote a few programs to read/write variable and fixed length records. Variable length records are pretty much regular ascii files (perhaps delimited with a comma) with […]
