Wherever you may use a blank when specifying an option, you may also specify as many blanks or comments as you wish.
However, if a comment is specified in %PROCESS line or in a line in an options file, then the comment must end on the same line as which it begins.
Similarly, if a comment starts in the command line or the PARM= specification, then it must also end there.
The same rule applies to strings: if a string is specified in %PROCESS line or in a line in an options file, then the string must end on the same line as which it begins. Similarly, if a string starts in the command line or the PARM= specification, then it must also end there.
