Things are tough right now ...

They're tough for everyone :( But when coronavirus hit here in the UK, the museum had to close its doors to the public, and we lost practically all our income overnight.

Please Donate Via Just GivingNo visitors, no workshops, no events, no school visits... no income. We know that things are tough for everyone right now, but if you can afford to help us through these tough times please donate what you can.

There's over 36,000 exhibits here! That should keep you occupied for a bit - get searching!

Amazon review:
For programming enthusiasts, this work is a gold mine. It describes the all-important techniques for successful programming. The following proverbs are described generously
throughout the book:
o Don't panic
o Problem definition is important
o Document early and continuously
o Plan and think first-code later
o Proceed top/down
o Code logically
o Use PERFORM and CALL verbs
o Comment effectively and use mnemonic words
o Get the syntax correct
o Plan for customizations
o Desk check your work
o Have someone else read your work
o Don't be afraid to start over or to make a major customization
or improvement


The author shows how to isolate key program messages in the data division and the wisdom of avoiding non-standard COBOL features.

An example of top/down programming follows:

describe input files
if either input file is missing or is labelled incorrectly
then let the operating system generate an error message
else if either input file is empty
then write appropriate message to system console
else prepare for payroll and report generation
generate payroll and report
clean up after generation

The author asks that programmers write simple code that is easy to read, interpret and re-create if the need arises. In addition. it is important to avoid nonstandard features.
This book has a wealth of programming standards information which
will prove invaluable in the field. The book is well worth the money.
