#DELTA Built-In Function
Variable Control Commands
Commands in #DELTA macros can push, pop, set, and manipulate variables. All these
commands (except the ^\command) must be immediately followed by a variable name;
the variable name must be terminated by a dollar sign ($). Table 9-7 summarizes the
syntax and effects of these commands. Full descriptions follow Table 9-9 on
page 9-121.
\ Converts number in
text to value in X
-X = (P)
x\ Puts x in text Text value of x
inserted at P
P = P + size
* You can modify the I, S, and :T commands with the @ flag to change the text delimiter from $ to another
character; for example: @I/text/
