Munger
m = expr(mno);
c = Name Expr(m) || "xyz";
show(c);
//result is "mnoxyz"
m=char(expr(mno));
c=m || "xyz";
show(c);
//result is "mnoxyz"
Concat Items() converts a list of string expressions into a single string, with each item separated by a
delimiter. If unspecified, the delimiter is a blank. Its syntax is
resultString = Concat Items ({list of strings}, );
For example,
a = {“ABC”, “DEF”, “HIJ”};
result = Concat Items(a, “/”);
returns
“ABC/DEF/HIJ”
Alternatively,
returns
result = Concat Items(a);
“ABC DEF HIJ”
Munger works many different ways, depending on what you specify for its arguments:
Munger(string, offset, find | length, );
Table 6.7 Munger behaviors for various types of arguments
Find, length, and replace arguments
If you specify a string as the find and specify no
replace string, Munger returns the position (after
offset) of the first occurrence find string.
If you specify a positive integer as the length and
specify no replace string, Munger returns the
characters from offset to offset + length.
If you specify a string as the find and specify a
replace string, Munger replaces the first occurrence
after offset of text with replace.
Example
Munger("the quick brown fox", 1,
"quick");
5
Munger("the quick brown fox",1,5);
"the q"
Munger("the quick brown fox", 1, "quick",
"fast");
"the fast brown fox"
