A value that contains blank characters must be surrounded with delimiters. Valid delimiters for a global variable value are single quotes, parentheses, and double quotes. When the delimiters are double quotes, the double quotes are included as part of the global variable.
When a SET GLOBAL command is entered from a linear proc and the variable value spans multiple lines, the value must be enclosed in quotes and a continuation character (+) must be used in the first position of each line. When the delimiters are double quotes, the double quotes are included as part of the global variable value. Parentheses cannot be used as a delimiter when spanning multiple lines.
