ID$–Identification Line Routine
Error Return
If ID$ takes the error return, either A1 or A2 contains a negative error code. If the error
occurred in ID$, A1 contains the error code. If the error occurred in SFDT$, A2 contains
the error code.
• ID$ error codes (returned in A1)
-01 An outdated version of the ID$ packet is being used.
• SFDT$ error codes (returned in A2)
-01 through -05 SFDT$ routine error; see Section 22.
The error code is also stored in the packet, in ERRCODE.
ID$ Output
The output ID$ generates may be one or more lines. This depends on the length of the
processor/program description and specified options. For each line of ID$ output, a print
control word is constructed (line spacing, image length, image address) and stored
sequentially in the ID$ packet starting with word 10. The number of print control words
constructed is stored in S6 of word 0 of the ID$ packet.
The following procedure simplifies printing of the ID$ output:
I$DPRINT pktaddr
where pktaddr is the address of the ID$ packet.
This procedure performs an APRINT$ for each print control word. It may be called from
the I$D$ PROC by setting option bit 31.
All output from ID$ is directed to the current print file.
Normal Return
If the normal return occurs, the first print control word is returned in A0.
