Examples:
E1. UD IC,300,X51,X52,X60,X65 (key is explicit number)
E2. UD IC,X90,X40,X35,X34,X10 (key is contained in register)
E3. UD IC,I,X30,X31 (key is the DO-LOOP index)
.DOCUMENT FILE: ADC998
[Enter the name of the document file previously created
by a 'SD' command or by operations such as 'PK']
[In example E1, let's say the document file has the first
490 keys filled. The command listed above will cause all
490 x 4 numbers of the document file to be stored for
future access within this session, and will fill
registers X51,X52,X60, and X65 with the values stored
under key 300. Subsequent access to any other key
present in the file (namely 1 ... 490),
e.g.
UD IC,410,X51,X52,X60,X65
will quickly look up the values stored under key
410 in the in-core image, without the need to access the
file.
IMPORTANT: only a imited number of document files may be accessed concurrently with 'UD IC'. Once the limit is reached one of the current files must be cleared by a 'UD ICE' command. An attempt to apply 'UD IC' to a additional document file before execution of a 'UD ICE' command to free the area reserved for data from an existing file will result in an error message.]
