11.7 Symbols
---------------------------------------------------------------
The symbol library consists of 5 separate libraries:
No. 1 (LIB1.PTF): DIN symbols (later EG-
Standard symbols).
No. 2 (LIB2.PTF): L&G symbols
No. 3 (LIB3.PTF): ISC symbols (the symbols in
this library are needed for displaying pic-
tures which were drawn on ISC units).
No. 4 (LIB4.PTF): MA-specific symbols (e.g. a
pump symbol which differs from the ones
in library No.1).
No. 5 (LIB5.PTF): Project-specific symbols.
Note: When editing libraries 4 and 5, please take into account
that their maximum size is limited to 60,000 bytes (for files
LIB4.PTF and LIB5.PTF).
Never, under any circumstances, make changes to symbol
libraries No. 1, 2 and 3.
The appendix "List of Symbols" lists all the symbols con-
tained in the libraries 1, 2 and 3.
General remarks:
Depending on the chosen picture background, the
symbols drawn in white on black or in black on white are
not visible.
<%>, however, inverts the colour display: White becomes
black and vice versa.
Concerning library No. 3:
The ISC macros are numbered from 0 to 255. In "Insight,"
on the other hand, the numbering in all libraries runs from
1 to 256.
The ISC characters, from which the ISC macros are com-
posed, occupy, in the 8:1 zoomed Picture Editor, 5 grid
points horizontally and about 6,5 grid points vertically.
