RE: dynamically naming variables
Here is a quick example of dynamic variable usage. cfset listVarNames = "foo,bar,dynamic,variables,rule" cfloop list="#listVarNames#" index="i" cfset "#i#DynamicVars" = "#i#DynamicVars" cfoutput#Evaluate(i "DynamicVars")#/cfoutput /cfloop cfoutputbr#fooDynamicVars#br#barDynamicvars#br#dynamicDynamicVars#b r#variablesDynamicVars#br#ruleDynamicVars#/cfoutput OUTPUTS: fooDynamicVars barDynamicVars dynamicDynamicVars variablesDynamicVars ruleDynamicVars fooDynamicVars barDynamicVars dynamicDynamicVars variablesDynamicVars ruleDynamicVars Thats all it takes. (sneaky ehh?:) There are a few "rules" if you will about your dynamic variables and the names they can have numbers, letters and underscores. You must start a variable with a letter. CF Interprets upper and lower case to be the same , no case sensitivity. Well, that's a quick and dirty version of the rules for using dynamic variables (and cf variables in general) You cant really "assign" a value to a coldfusion function, CF does nto grock that. If what your trying to do did not fit into the rules I just mentioned you probably can't do it :) :-) BTW, if you find the cfset line confusing replace it with cfset "#i#DynamicVars" = "Just a plain ole string going into my dynamic variable" Jeremy Allen elliptIQ Inc. -Original Message- From: Jay Brushett [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 20, 2000 10:54 AM To: CF-Talk Subject: dynamically naming variables Hi, I need to use the Evaluate function to dynamically name variables in a cfloop.

RE: dynamically naming variables
This is how i use dynamic variable names on the left side of a cfset there's probably other ways to do it too CFLOOP from="1" to="20" index="i" CFSET varname = "myvar" i CFSET "#varname#" = i /CFLOOP Allan Pichler Machine Dreams Inc. -Original Message- From: Jay Brushett [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 20, 2000 7:54 AM To: CF-Talk Subject: dynamically naming variables Hi, I need to use the Evaluate function to dynamically name variables in a cfloop.
