4.6 Source Code Management
Various tools assist in management of source code. To assist in seeing the "big picture" of source code organizaation
and navigation, the following are provided:
QX ( n) displays the 60 block index page that contains block n without changing the Editor's focus.
NX
displays a QX of the index page following that most recently displayed.
BX
displays a QX of the index page preceding that most recently displayed.
SX
toggles between the QX most recently displayed and shadows for same.
AX
displays a QX of the index page containing the block on which the Editor is focused.
LOCATE (_) If the word following LOCATE is currently defined in the dictionary, displays the source block
that defined it, if possible. The EDITOR cursor position is not included in the LOCATE field on this
system since its cost is too great in 16-bit environments.
4.6.1 Source Code Organization
The code is grossly organized in "index pages" of sixty blocks, hence the relevance of the above display functions.
Assignments are as follow:
Origin Content
30
0
Binary nucleus image in [0..8].
entitlements follow, along with
utilities.
9 is the HI load block. Basic
DISKING and nucleus maintenance
60
Nucleus source for target compilation, including the Editor.
120
Additional entitlements and options. This page and the one at 180 may be
re-used for application code if SPI flash is being used as main mass
storage in the configuration with 480 blocks of backup.
180
Math routines.
240
Benchmarks and test code, will eventually move to 480.
300
