SET ALIAS (continued)

Special Characters as Aliases

When an alphanumeric alias is used, it must be surrounded by spaces or punctuation in a command. An exception to this requirement is made if any of the following characters are specified alone as a single-character alias for any term or operator other than AND, OR, or NOT:

dot	.		pound sign	#
ampersand	&		percent sign	%
dollar sign	$		backslash	\
at sign	@

In these cases, Dialog replaces all occurrences (regardless of spacing and/or punctuation) of the original text with the character specified in the SET ALIAS command.

Caution: Use the special character option with care, particularly in the case of the . (dot) and the @ (at sign). The dot is commonly used for numeric values (i.e., decimal values) and the @ is used in the TRADEMARKSCAN^® files in the TR=field. If you use one of these symbols as an alias, remember to turn the alias off (see Turning Aliases On and Off) before searching a file in which the symbol would cause a conflict.

• To use a special character as an alias:

?set alias % (s)
% is set ON as an alias for (S). 
?select simulation%hydrogeolog?
           32984  SIMULATION
           79919  HYDROGEOLOG?
      S1      96  SIMULATION(S)HYDROGEOLOG?
?type s1/ti/1
