Paper No 19: Displayers and Print Programs V3.5
R E Thomas
25 November 1975
The following changes have been made in V3.5.
DISPLAYERS
- A new monitor command:
SPEED OF VECTOR
allows the operator to select the vector speed 8, 4, 2 or 1 msecs.
- All displayers now reside in directory MON.
The host packages are being changed to use SPEED OF VECTOR to differentiate between
Hardcopy (8 msecs) and 35/16mm (2 msecs ).
No separate 35/16mm displayer is now required, and no directories RF, HF, MF or CF are used.
PRINT PROGRAMS AND SD4020 SIMULATOR
- There is now a patch tape set up for these programs,
along the lines of that used for the displayers. Currently, the following files
in SYM will assemble an ACD version.

48 times fiche programs can be generated by modifying the 42 times versions,
or by assembling the appropriate fiche routines with
Fi48.==I
instead of
FI42.==I
The other two versions of the SD4020 simulator can equally be obtained by
modifying HC, or by assembling SD4HC with:
MM16.==1
MM35.==1
instead of
HC..==1
- The monitor screen character sizes have been altered to be as large as possible.
ICL 7-track print has a 556 bpi default.
- The ICL fiche programs have a new monitor command to control the meaning of PFCC's:
COMMA RECORD
When set to 0, the program will ignore any title records on tape and recognise #11 instead.
When set to 1, the comma record will be interpreted as a title (#34).
- The following modifications must still be inserted after assembly:
ICL Fiche EXTRACT
and
TITLE
suited to PRFICHE title extraction
Note that if the 48 times versions of ICL fiche are generated by hand from the 42 times
versions, it is necessary to re-input the TITLE after the pitch, margin, images
and size of title have been reset
- IBM 7-track print programs will now accept the BCD code generated by the "translate on"
option on the 360.
The basic original IBM 7-track accepts "true" BCD.
- The standard for 7-track print is:
No carriage controls
Fixed blocking
No labels
- III Version 2 fiche, 7-track IBM, is in use since V3 has not yet been
sent. No , title record is available.
- The standard IBM 9-track print is:
ASA (ANSI) carriage controls
Variable blocking
Labelled
The TN-chain characters are not available.
