enscript with greenbar output

The following commands are taken from a link Professor Rene’ Ferland’s pointed to on his website. enscript –font=Courier-Bold@8 -l -H3 -r –margins=25:25:40:40 -p cobol01.ps cobol01.cob ps2pdf cobol01.ps cobol01.pdf The professor’s script used Ghostscript rather than ps2pdf. The above 2 commands can be combined into one. enscript –font=Courier-Bold@8 -l -H3 -r –margins=25:25:40:40 -p – cobol01.cob | […]

And the COBOL versions that […]

UNPK and ED

ED on the other hand can also can also unpack packed numbers into zoned decimal…but these are printable. I guess I knew at one time but […]

Assembler MVC basics

Playing with S/370 assembler specifically the simple MVC instruction. Realized I’d forgotten basics by examining storage with the SNAP macro, after trying various moves. Came to realize that the length is only determined by the first operand. Verified this later by looking at yellow card. Figured out one way to move values to a 80 […]
