#!F-adobe-helvetica-medium-r-normal--18* #!N #!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 #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Lall514,dxall515 h Reserved Words #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
