F$EDIT(string, edit-list)
string
Specifies a character string to be edited. Quoted sections of the
string are not edited.
edit-list
Specifies a character string containing one or more of the
following keywords that specify the types of edits to be made
to the string:
Edit Action
COLLAPSE Removes all spaces or tabs.
COMPRESS Replaces multiple spaces or tabs with a single
space.
LOWERCASE Changes all uppercase characters to lowercase.
TRIM Removes leading and trailing spaces or tabs.
UNCOMMENT Removes comments.
UPCASE Changes all lowercase characters to uppercase.
If you specify more than one keyword, separate them with commas
(,). Do not abbreviate these keywords.
Edits are not applied to quoted sections of strings; therefore,
if a string contains quotation marks (" "), the characters
within the quotation marks are not affected by the edits
specified in the edit list.
