For additional information about #DELTA and STRUCT variables, see the TACL
Reference Manual. For examples showing the use of STRUCT variables with SPI and
EMS, see Section 7, “Using Programmatic Interfaces.”
The following paragraphs describe how to use string manipulation functions and
commands.
Note Variable levels that contain TACL code contain special internal multicharacter representations of [, |,
and ]. When you use character oriented functions, be aware that these representations are counted as
multiple characters; they contain unprintable characters that are subject to change from one release of
TACL to another.
Line and Character
Built-In Functions
The functions in Table 2-1 operate on the contents of variables; each of these functions
performs an action and/or returns a result. There are two types of functions—one
accepts a character address; the other accepts a line address. Table 2-1 lists both types
of built-in functions; a dash indicates that there is no equivalent function or command.
