Now this is precious: "For in-stream data sets: with the SH option, trailing blanks are not truncated. Records in in-stream data sets are concatenated with blanks as separator characters, and the string remaining after the SH token is passed as a single argument to a /bin/sh -c command. For the PGM option, the string is divided not only at line boundaries but also at horizontal white space within a line. "
Where is it documented how STDPARM is treated for other datasets and Unix files? If the data after the leading shell are not treated as a single parameter, why not? -- Shmuel (Seymour J.)

In Unix, semicolons are command separators, not a continuation indicator. The actual command continuation character is "\", but that is only needed just prior to an EOL character. It would appear that in this environment no end-of-line characters are seen, so unix just sees "SH su <whitespace> SH ...". Without the semicolon the shell sees the command "su SH", which is an attempt to switch to the context of user "SH". In the absence of a recognized EOL/ENTER to indicate end of command, the semicolon must be used between commands -- although putting an extra one at the end doesn't hurt -- it just sees a null command at the end. This requirement may not be documented. They may just assume that everyone familiar with Unix will of course "know" this if they describe the STDPARM file as being treated as a single string or a single line with no EOL forced at the end of each record.
