In the first page of the PRG BRCH menu, pressing the shift keys before pressing any menu key provides a handy typing shortcut for programmers. In all these cases, the cursor is placed at the end of the first command. Thus these shifted keys can be thought of as “program structure delimiters”. While entering a program,
! IF | types | IF THEN END |
@IF | types | IF THEN ELSE END |
! CASE | types | CASE THEN END END |
@CASE | types | THEN END |
!START | types | START NEXT |
@START | types | START STEP |
!FOR | types | FOR NEXT |
@FOR | types | FOR STEP |
!DO | types | DO UNTIL END |
!WHILE | types | WHILE REPEAT END |
!IFERR | types | IFERR THEN END |
@IFERR | types | IFERR THEN ELSE END |
In the EDIT menu, @%±SKIP%and @%SKIP²% perform
In the units menus, pressing a unit menu key multiplies by that unit, whereas @%UNIT% divides by that unit.
!%UNIT% converts to that unit, if possible.
In program mode, @%UNIT% returns '1_unit' /, while !%UNIT% returns '1_unit' CONVERT, where “unit” is the unit corresponding to the menu key.
