Program Trace Routine
LINE
Adjusts the length of the line printed by SNOOPY. If "LINE /" is entered, the line
length set is the default value of 132 decimal = 204 octal. Otherwise, the parameter
given to LINE must be an octal number denoting the line length for the device in
use. As indicated, the default value is 132 decimal = 204 octal for devices such as
DCT 500 terminals.
For a UNISCOPE or UTS Display terminal, use “LINE 116” with alternate print files
(see the ALTPRT command), “LINE 204” may be the most convenient. The effect
of a LINE command is canceled by the next LINE command or by program
termination. The previous value will be printed as “WAS nnn”. This value is also
printed when SNOOPY signs on unless NO HDG is set.
number
Has the same effect as a SKIP n GO sequence (where n is the number). See SKIP
command. The number is in octal.
PRINT (P)
Allows the amount of printing to be modified. The PRINT command recognizes only
one parameter at a time. If an invalid parameter or no parameter is specified, the
F parameter is assumed. The parameters are:
C
E
F
N
P
Produces a printout omitting extraneous formatting spaces.
Produces an expanded printout including formatting spaces. The E mode is
effective until a PRINT C is encountered.
Produces a full printout consisting of each instruction, its location, and the
contents of main storage and registers (in before/after form if the value
changed). For certain Executive Requests, the contents of the associated
packet are also dumped. This is the default mode.
Suppresses printout. This provides a means of skipping long sections of
irrelevant code.
Produces a printout of the instructions but not referenced main storage or
Executive Request packets. If SNOOPY is in the N mode, the P mode is entered
automatically upon the occurrence of an RBK contingency or encountering a
BREAK-specified break condition.
