Wherever you can use a blank when specifying an option, you can also specify as many blanks or comments as you wish. However, there are a few rules that you must take notice of.
If a comment is specified in %PROCESS line or in a line in an options file, the comment must end on the same line as which it begins.
Similarly, if a comment starts in the command line or in the PARM= specification, 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, the string must end on the same line as which it begins. Similarly, if a string starts in the command line or in the PARM= specification, it must also end there.
