54 ;;; 93-01-07 V0.1 ALi Works for the first time.
55 ;;; 92-01-11 V0.2 ALi rexx-calc-indent totally rewritten.
56 ;;; 93-03-08 V0.3 JB rexx-indent-and-newline-and-indent added.
57 ;;; Abbrev-table containing 173 entries created.
58 ;;; rexx-check-expansion added.
59 ;;; rexx-mode enables use of abbrev-table.
60 ;;; 93-03-15 V0.4 ALi abbrev-mode removed, better to call
61 ;;; (abbrev-mode 1) from the hook.
62 ;;; case-fold-search set to t to recognize capital
63 ;;; letters in keywords.
64 ;;; Old (setq case-fold-search nil) removed which
65 ;;; prevented the recognition of END.
66 ;;; rexx-indent-and-newline-and-indent renamed to
67 ;;; rexx-indent-newline-indent.
68 ;;; rexx-i-n-i now only expands abbrevs when
69 ;;; buffer is in abbrev-mode.
70 ;;; New rexx-newline-and-indent added.
71 ;;; 93-03-20 ALi A serious bug in the routine for checking
72 ;;; strings and comments found and fixed.

357 The relative offset of the \"end\" statement. 0 places it in the

368 If you have set rexx-end-indent to a nonzero value, you probably want to
369 remap RETURN to rexx-indent-newline-indent. It makes sure that lines
370 indents correctly when you press RETURN.
372 An extensive abbreviation table consisting of all the keywords of REXX are
373 supplied. Expanded keywords are converted into upper case making it
374 easier to distinguish them. To use this feature the buffer must be in
375 abbrev-mode. (See example below.)

378 no args, if that value is non-nil.
