A CHART FOR READY REFERENCE
The following chart contains summary information about each of the personalization bytes discussed
in this section. The addresses are given relative to the start of BASIC (the “ORG +“ form), and, for
those whose BASIC starts at 3584 (0E00H), the actual addresses in decimal and hex are also given.
ORG+6 & ORG+7 (3590 & 3591 or 0E06 & 0E07)
[ENDBAS]
These two locations contain the low and high bytes, respectively, of the last address taken up by the
BASIC interpreter itself, and may be modified to contain a lower address in order to shrink BASIC.
ORG+9 & ORG+10 (3593 & 3594 or OE09H & 0E0AH)
HIGHMEM]
Contains lower and upper bytes, respectively, of highest address in RAM which BASIC may use for
program/data area. Standard value: 255 and 227 respectively (corresponding to E3FFH).
ORG+14 (3598 or 0E0EH)
Initial line length. Standard value: 80
[LINECT]
ORG+15 (3599 or 0E0FH)
[AUTOST]
Controls turnkey autostart. Zero byte means autostart engaged. Standard value: 1 (turnkey operation
required).
ORG+16 (3600 or 0E10H)
[BOOTPR]
Corresponds to first two hex digits in bootstrap PROM address for your system. Standard value: 232
(E8H)
ORG+19 (3603 or 0E13H)
[PAGES]
Controls paging mode for program listings. If paging is desired, this should contain the number of
lines in a terminal page. A zero value means no paging will occur. Standard value: 24
ORG+23 (3607 or 0E17H)
[DELECHO]
Character to be echoed in response to a single character deletion. Standard value: 08 (corresponds
to backspace character).
ORG+24 (3608 or 0E18H)
[PANICOK]
Controls use of <control-C> for BASIC program interruption. If this byte is 0, <control-C> causes
interruptions. When the value is non zero, <control-C> interruptions are disabled. Standard value:
0 that enables interruption management.
