Quoting mechanisms

FMLI supports quoting mechanisms, similar to those used in the UNIX system shell, for disabling the meaning of special characters in a string. Each quoting mechanism has a different function, as defined below.

• Backslash (\): A backslash causes the next single character to be taken literally. That is, any special meaning of the character following a backslash is turned off. (In some cases, multiple backslashes may be required to escape the special meaning of a character.)

• Single quotes (' '): Any string inside of single quotes is taken literally and as a unit. Inside single quotes, only the backslash (\) has special meaning.

• Double quotes (""): Double quotes group the text between them as a unit, but still allow variable expansion and the use of backquotes. Inside double quotes, only backslash (\), backquote (`), and dollar sign ($) retain their special meanings. Carriage returns inside double quotes are enforced.

• Backquotes (` `): (Backquoted expressions are discussed in detail in the next section.) Any statement or series of statements may be enclosed in backquotes with the result that such a backquoted expression evaluates to the output of the last statement. Statements may be UNIX system executables or FMLI built-in utilities. Backquotes cannot be nested, except as provided for in regex. (See the regex(1fmli) manual page for more information.)

  NOTE: If a statement run in a backquoted expression changes the stty(1) setting, the FMLI session may be corrupted. Frames may not display correctly and the FMLI command line may not function (the latter occurs if <Return> is mapped to LINEFEED or to LINEFEED <Return>).
