TFORMCVT: Converting From TGAL to TFORM

Tips
If the TGAL required blank character is specified as the trigger
character, TFORMCVT does not double it in the output (when it’s not
in column 1); instead, it translates it to the trigger followed by “#”.
TFORMCVT doubles the trigger character (when it’s not in column 1)
in all text lines. TFORMCVT also checks the strings in the following
commands for triggers: FOOT, HEAD, OUT, SECT, SUBHEAD, TAG,
TODAY, and VERSION.
The “$$” command doesn’t cause a break in TGAL, but does cause a
break in zFORM. A situation where a break doesn’t actually occur
through TFORMCVT is one in which one (or both) of the first two lines
of a paragraph begin with “$$.” The example below shows the
difference between the TGAL input and the TFORMCVT output.
TGAL Input:
$$ Mary had a little snake
$$ Whose scales were green as grass,
TFORMCVT Output:
\KEEP 5
\KEEP 5
\INDENT ON 4
Mary had a little snake
Whose scales were green as grass,
\INDENT OFF
