#!CSeaGreen #!N  #!Rall513 Naming Variables 
and Macros #!N #!EC #!N #!N You can name the variables 
and macros with  #!F-adobe-times-medium-i-normal--18*   identifiers #!EF . Identifiers are sequences of 
characters selected from the following: #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N 
#!I30 #!N o Uppercase alphabetic characters (  #!F-adobe-times-bold-r-normal--18*   A-Z #!EF ) 
#!N #!I30 #!N o Lowercase alphabetic characters (  #!F-adobe-times-bold-r-normal--18*   a-z #!EF 
) #!N #!I30 #!N o Numerals (  #!F-adobe-times-bold-r-normal--18*   0-9 #!EF ) 
#!N #!I30 #!N o Special characters: #!N #!I0 #!N  #!F-adobe-times-medium-r-normal--18*   #!N 
#!N #!I30 #!N - Underscore (  #!F-adobe-times-bold-r-normal--18*   _ #!EF ) #!N 
#!I30 #!N - Single quote (  #!F-adobe-times-bold-r-normal--18*   ' #!EF ) #!N 
#!I30 #!N - "At" sign (  #!F-adobe-times-bold-r-normal--18*   @ #!EF ) #!N 
#!I0 #!N #!EF #!N #!N #!I0 #!N #!EF #!N All identifiers 
must start with either an alphabetic character, an underscore (_), or 
an "at" sign (@). Remember that the Data Explorer script language 
is case sensitive: identifiers that differ in the case of at 
least one character are considered to be different identifiers. Identifiers are 
currently limited to a length of 200 characters. #!N Note: IBM 
reserves the definition and use of most identifiers that begin with 
@. However, there are some built-in @ variables that you can 
set; these are discussed in  #!Lsdxsc,dxall548 h Using Data Explorer Script Commands  #!EL  . #!N #!N #!N The 
following are valid, unique identifiers: #!N #!N #!CForestGreen #!N  #!F-adobe-courier-bold-r-normal--18*   #!N 
ComputeSine #!N Compute_Sine #!N c0mpute_sine #!N compute_s1ne #!N compute_sine' #!EF #!N 
#!N #!EC #!N #!N Identifiers can be used as: #!N #!I0 
#!N  #!F-adobe-times-medium-r-normal--18*   #!N #!N #!I30 #!N o variable names #!N #!I30 
#!N o function names. #!N #!I0 #!N #!EF #!N #!N #!N 
Some identifiers are reserved and cannot be used as a variable 
or a function name. Every other identifier can be used both 
as a variable and as a function name. The proper use 
of the identifier is determined by its context. #!N #!N #!N
