Comments |
| X - examine memory |
[start addr][,end addr]X |
Displays contents of memory. |
| A - address display mode |
Ax |
Where x is the mode, h being hexadecimal and s being
symbolic. |
| D - data display mode |
[width]Dx |
Width is number of bytes to display. x is mode: h - hexadecimal s - symbolic a - ASCII |
| H - display value in hex |
[addr expression]H |
Displays expression in hex. Can be used to display
value of symbols. |
| Y - display value symbolically |
[addr expression]Y |
Opposite of above. |
| V - set screen size |
[[bottom line addr],lines nr]V |
Defines bounds of screen. Bottom line addr can be
from E0 to E7 (0 to 23), while linesnr is the window size from 1 to 24. |
| C - change register/memory |
[start addr/symbol],data exprC |
Allows memory/registers to be changed. Examples: 1000,22C - change value at location 1000 to 22 |
| C - change memory |
[start addr/symbol]Cs |
Allows a string of data to be written. s is as follows: symbolic processor instructions (Z80 assembly language): 1000Cld (hl),a # followed by hex digits: 1000C#66 ' followed by ASCII characters: 1000'Wang |
| M - move data |
[source addr[,dest addr[,count]]]Mx |
Move data from source to dest, moving number of bytes
specified by count. x is optional, and specifies the destination target: s - To slave (specified by current Unit setting) m - To Master (from slave specified by current Unit setting): 1000,1000,20Ms - Would move 20(hex) bytes from the Slave at address 1000 to address 1000 in the Master. |
| G - Go |
[break count][,start addr]G |
Start execution at [start addr]. break count sets
the number of breakpoints that can pass before control is returned to the
debugger. |
| S -Single step |
[count]S |
Step through [count] instructions. |
| E - Execute disk command |
[page addr][,sector][,page count],[drive address]Ex |
Perform disk operation, where x is the operation
to perform: r - read w - write f - format c - compare u - release disk drive The read/write commands operate on the current Unit number. |
| U - Set current Unit |
[unit address]U |
Sets unit for operations. 00 = Master. |
| I - IPL current Unit |
[address]I |
IPL (restart) slave to address. Does nothing if the
Unit is 00 (master). |
| B - Set symbol |
[addr exp]Bsymbol |
Assigns symbol name to address expression: 6e00Biplinit |
| Z - Clear symbol |
Zsymbol |
Removes symbol from table. |
