They do an incredible job of some sort of 2-layer PDFs which are simultaneously images (even with fingerprints) and searchable text. I've found: https://en.wikipedia.org/wiki/EBCDIC_037 https://en.wikipedia.org/wiki/EBCDIC_037-2 https://en.wikipedia.org/wiki/EBCDIC_1047 Differences in a handful of code points; not enough to bring world peace or solve climate change.
On Linux, the script below compares the output of "dd conv={ebcdic|ibm}" to pages 037, 500, and 1047. The best match seems to be "conv-ibm" to IBM-1047. I don't believe that the "dd" utility per se motivated a serious requirement, but does "dd conv=ibm" reflect otherwise prevalent practice? (And we still have the LF-NL irritant.) # ################################# #! /bin/sh -x S=$( awk 'BEGIN { for ( I=32; I<128; I++ ) printf( "%c", I ) }'; ) around() { echo; echo; echo EBCDIC "$1" printf %s "$S" | dd conv=ebcdic | iconv -f "$1" -t ISO8859-1 echo; echo IBM "$1" printf '%s\n' "$S" printf %s "$S" | dd conv=ibm | iconv -f "$1" -t ISO8859-1 } around CSIBM037 around CSIBM500 around IBM-1047 echo exit # ################################# Thanks again, gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
