- ;;; HISTORY
- ;;; 93-01-07 V0.1 ALi Works for the first time.
- ;;; 92-01-11 V0.2 ALi rexx-calc-indent totally rewritten.
- ;;; 93-03-08 V0.3 JB rexx-indent-and-newline-and-indent added.
- ;;; Abbrev-table containing 173 entries created.
- ;;; rexx-check-expansion added.
- ;;; rexx-mode enables use of abbrev-table.
- ;;; 93-03-15 V0.4 ALi abbrev-mode removed, better to call
- ;;; (abbrev-mode 1) from the hook.
- ;;; case-fold-search set to t to recognize capital
- ;;; letters in keywords.
- ;;; Old (setq case-fold-search nil) removed which
- ;;; prevented the recognition of END.
- ;;; rexx-indent-and-newline-and-indent renamed to
- ;;; rexx-indent-newline-indent.
- ;;; rexx-i-n-i now only expands abbrevs when
- ;;; buffer is in abbrev-mode.
- ;;; New rexx-newline-and-indent added.
- ;;; 93-03-20 ALi A serious bug in the routine for checking
- ;;; strings and comments found and fixed.
- ;;; V1.0 Relesed!

- Variables controlling indentation style:
- rexx-indent
- The basic indentation for do-blocks.
- rexx-end-indent
- The relative offset of the \"end\" statement. 0 places it in the
- same column as the statements of the block. Setting it to the same
- value as rexx-indent places the \"end\" under the do-line.
- rexx-cont-indent
- The indention for lines following \"then\", \"else\" and \",\"
- (continued) lines.
- rexx-tab-always-indent
- Non-nil means TAB in REXX mode should always reindent the current
- line, regardless of where in the line the point is when the TAB
- command is used.
-
- If you have set rexx-end-indent to a nonzero value, you probably want to
- remap RETURN to rexx-indent-newline-indent. It makes sure that lines
- indents correctly when you press RETURN.
-
- An extensive abbrevation table consisting of all the keywords of REXX are
- supplied. Expanded keywords are converted into upper case making it
- easier to distinguish them. To use this feature the buffer must be in
- abbrev-mode. (See example below.)
-
- Turning on REXX mode calls the value of the variable rexx-mode-hook with
- no args, if that value is non-nil.
-
- For example:
- (setq rexx-mode-hook '(lambda ()
- (setq rexx-indent 4)
- (setq rexx-end-indent 4)
- (setq rexx-cont-indent 4)
- (local-set-key \"\\C-m\" 'rexx-indent-newline-indent)
- (abbrev-mode 1)
- ))
-
- will make the END aligned with the DO/SELECT. It will indent blocks and
- IF-statenents four steps and make sure that the END jumps into the
- correct position when RETURN is pressed. Finaly it will use the abbrev
- table to convert all REXX keywords into upper case."
