2.2.1 Explanation of the "T"-Version ____________________________________
The "T" version is for use on terminals which display only
upper-case characters.
On upper/lower case terminals, Labels and format codes (see
Section 4) are displayed in the case in which they are entered.
On upper-case-only terminals, however, there is no distinction
made when these two kinds of special purpose text are displayed.
That is, no percent or double percent signs are displayed to
indicate upper case characters. Since it is impossible to
Labels and macros differentiate between upper and lower case, _________________
should always be specified exclusively in lower case ________________________________________________________ when an
upper-case terminal is likely to be used. In addition, certain
commands (FLIP, CAPITALIZE, and UNCAPITALIZE) will force all
macro names included in their <scope>'s to lower case, making it
always desirable to ______ specify macro names in lower case.
2.2.1.1 Representing Upper-Case Characters (in the "T" version) _______________________________________________________________
It is possible to represent capital letters by preceding them
by the special capitalize character ("%").
Since the percent signs indicating upper-case are not actually
not part of the file, it is ___ possible to capitalize characters by
inserting percent or double percent signs, or by surrounding a
text string with double percent signs using the SURROUND
The percent signs must be entered with the characters command. ______________________________________________________
either in Command or Input Mode _______________________________.
A string of capital letters can be represented using the
multi-cap _________ delimiters ("%%") at each end of the string.
