When testing
ConPLAN user programs, it will be noted that interpreting data in the emulated data areas can be a rather arduous task, as data in ICL format cannot be readily understood when displayed in any of the standard IDA/AID display formats. IDA/AID lack the facility to display: • Octal numbers
• ICL characters in 6-bit code The test facility $AID is designed to bridge this gap. It is based on the BS2000 command /INTR (Program interrupt), and is an integral feature of the conversion system. A ConPLAN
program can be stopped at any time, either by pressing [K2] or preferably, by setting an IDA/AID stop. Once in command mode, the command /INTR can be entered with or without parameters. The format is /INTR [[W]addr,[W]len]
| /INTR without parameters: Display the ICL accumulators X0-X7 both in octal and printable format. |
addr | The hexadecimal
start address of a memory area to be displayed both in octal and |
len | The decimal length of the memory area to be displayed. It can be specified in bytes or ICL Words (see parameter W) |
| W |
indicates ICL word format, i.e. if addresses from the assembler listing are used which follow the header: |
|
'VIRTUAL DATA STRUCTURE (WORDS)', the address must be preceded by W. Alternatively, one can use the symbolic data name and let IDA/AID find the byte address in memory (/DISPLAY command). Such an address is a byte address and must be entered without W to address the desired memory location. Similarly, in connection with len, W can be used to refer to a decimal length in ICL 24-bit words. len defaults to a byte length if W is not specified. |
Examples:
The commands | /INTR | D95,30 | | /INTR | D95,W10 | | /INTR | W487,30 | | /INTR | W487,W10 |
display 30 bytes of data beginning at location (dec) 357.
The commands display the ICL accumulators X0-X7 Note | After entering an /INTR command, BS2000 will resume execution of the user program unless a IDA/AID stop was explicitly set. |
