Option

Words For Almost-Non-Volatile Environment

---

NVRAM,WORDS( -- )  => "EXTENSIONS"

Print a list of WORDS in the NVRAM buffer. Try to show also the current value, atleast for NVRAM numbers and strings. Words can be added or changed with the help of NVRAM,SET or NVRAM,USE

Values in the NVRAM buffer will survive a COLD reboot, in many hosted environments however the NVRAM will be lost on program exit.

primitive code = [p4_nvram_words]

---

NVRAM,Z@( "varname" -- z-str )  => "EXTENSIONS"

Return the string pointer of the NVRAM string item, or null if no such item exists.

primitive code = [p4_nvram_z_fetch]

---

NVRAM,S@( "varname" -- str-ptr str-len )  => "EXTENSIONS"

Return the string span of the NVRAM string item, or double null if no such item exists.

primitive code = [p4_nvram_s_fetch]

---

NVRAM,?@( number "varname" -- number' )  => "EXTENSIONS"

Return the value of the NVRAM value item, or leave the original number untouched (i.e. the default value for your option).

primitive code = [p4_nvram_Q_fetch]

---

NVRAM,AS( str-ptr str-len "varname" -- )  => "EXTENSIONS"

set the NVRAM variable to the specified string.

Some NVRAM strings do not take effect until next COLD reboot.

primitive code = [p4_nvram_as]

---

NVRAM,TO( number "varname" -- )  => "EXTENSIONS"

set the NVRAM variable to the specified number.

Most NVRAM numbers do not take effect until next COLD reboot.

primitive code = [p4_nvram_to]
