Activating OpenBoot Help
The Forth Monitor contains an online help which can be activated by entering the
command help. Entering help creates the following screen output.
okahelpaa
Enter ‘help command−name’ or ‘help category−name’ for more help
(Use ONLY the first word of a category description)a
Examples: help select −or− help line
Main categories are:a
Numeric output
Radix (number base conversions)
Arithmetic
Memory access
Line editor
System and boot configuration parameters
Select I/O devices
Floppy eject
Power−on reset
Diag (diagnostic routines)
Resume execution
File download and boot
Nvramrc (making new commands permanent)
ok
A list of all available help categories is displayed. These categories may also contain
subcategories. To get help for special Forth words or subcategories, enter
help <name>
The online help shows you the Forth word, the parameter stack before and after execution
of the Forth word (before −− after), and a short description.
The online help of the Forth monitor is located in the boot PROM. This means that an
online help is not available for all Forth words.
Typical examples for how to get help for special Forth words or subcategories are given
below.

move ( src dest length −− ) copy length bytes from src to dest addressa
map? ( vaddr −− ) show memory map information for the virtual addressa
x? ( addr −− ) display the 64−bit number from location addra
l? ( addr −− ) display the 32−bit number from location addra
w? ( addr −− ) display the 16−bit number from location addra
c? ( addr −− ) display the 8−bit number from location addra
x@ ( addr −− n ) place on the stack the 64−bit data at location addra
