Section 5, “Expressions,” describes the constants, variables, operators, and
functions you can use to examine, evaluate, and convert various kinds of
data and to perform computations.
Section 6, “System Parameters,” contains a description of each system
parameter, set by the command interpreter’s PARAM command, that affect
the environment and activities of TFORM.
Appendix A, “Syntax Summary,” lists the syntax descriptions of all TFORM
commands, escape sequences, expressions, and functions.
Appendix B, “TFORM Messages,” lists all the TFORM error messages with
a summary of the intent of each.
Appendix C, “Limits and Defaults,” summarizes the minimum, maximum,
and default values for the various TFORM measurements and environment
settings.
Appendix D, “Comparison of TGAL and TFORM, “ correlates the TFORM
commands with the commands of Tandem’s earlier text formatter, TGAL.
Appendix E, “Converting from TGAL to TFORM,” describes the way that
the conversion program TFORMCVT converts, as precisely as possible,
commands in a TGAL-formatted file to their TFORM counterparts.
Appendix F, “Converting Between TFORM and T-TEXT,” describes the
way that the conversion program TFORMCVT operates bi-directionally to
convert, as precisely as possible, TFORM or T-TEXT commands to their
T-TEXT or TFORM counterparts.
Appendix G, “Examples of FUNCTION and MACRO Constructs,” presents
examples of FUNCTION and MACRO constructs. Each of the examples
provide comments describing various statements in the constructs, and the
MACRO constructs contain the macro invocation commands that run the
different macros.
Appendix H, “Fonts,” describes font characteristics in detail and how
printers load and select fonts.
