Grouping Commands
The format for grouping commands is as follows:
(compound-list)
Execute compound-list in a subshell environment; see Shell Execution Environment . Variable assignments and built-in commands that affect the environment shall not remain in effect after the list finishes.
{ compound-list;}
Execute compound-list in the current process environment. The semicolon shown here is an example of a control operator delimiting the } reserved word. Other delimiters are possible, as shown in Shell Grammar ; a <newline> is frequently used.

xmstringbytecompare
XmStringByteCompare(3X) XmStringByteCompare(3X)
NAME
XmStringByteCompare - A compound string function that indicates the results of a byte-by-byte comparison
SYNOPSIS
#include <Xm/Xm.h>
Boolean XmStringByteCompare (s1, s2)
XmString s1;
XmString s2;
DESCRIPTION
XmStringByteCompare returns a Boolean indicating the results of a byte-by-byte comparison of two compound strings.
In general, if two compound strings are created with the same (char *) string using XmStringCreateLocalized in the same language environ-
ment, the compound strings compare as equal. If two compound strings are created with the same (char *) string and the same font list ele-
ment tag set other than XmFONTLIST_DEFAULT_TAG using XmStringCreate, the strings compare as equal.
In some cases, once a compound string is put into a widget, that string is converted into an internal form to allow faster processing.
Part of the conversion process strips out unnecessary or redundant information. If an application then does an XtGetValues to retrieve a
compound string from a widget (specifically, Label and all of its subclasses), it is not guaranteed that the compound string returned is
byte-for-byte the same as the string given to the widget originally. Specifies a compound string to be compared with s2 Specifies a com-
pound string to be compared with s1
RETURN VALUE
Returns True if two compound strings are identical byte-by-byte.
