Ami missing something? Are >the programs broken? Any help appreciated. (Z/os V1.13) > Under OMVS on z/OS you can convert data to base64 with the "uuencode -m" command. This can be useful as a test to compare its results with the results of other programs that claim to convert data to base64. The "-m" switch makes it use base64 instead of its normal form of encoding. You just have to strip off or ignore the first and last line of the result if you only want the base64 part.
This example converts EBCDIC "foo" to base64 "hpaW". I use "printf" instead of "echo" because "echo" appends a newline which will also be converted to base64. printf "foo" | uuencode -m newfile which produces these 3 lines on the screen: begin-base64 000 newfile hpaW ==== The same command on x86 Linux servers that I use would produce "Zm9v" instead of "hpaW" because the input string is ASCII instead of EBCDIC. Here is an example with "echo", to show the effect of the newline added by "echo".\ echo "foo" | uuencode -m newfile begin-base64 000 newfile hpaWFQ== ==== Internet sites for base64 encoding would typically convert ASCII "foo" to base64 "Zm9v". One way to get this result under OMVS is to pass the string through "iconv", as in this example: printf "foo" | iconv -f IBM-1047 -t ISO8859-1 | uuencode -m newfile begin-base64 000 newfile Zm9v ==== I can also get the EBCDIC result on an x86 Linux server, like this: printf "foo" | iconv -t 1047 | uuencode -m newfile begin-base64 600 newfile hpaW ==== Bill ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
