Hi,

I need to change a hard-coded expression into a variable (stored in the app object). The expression has a variable - name of the alias - which may change in different parts of the app. Here is an example (close to actual case):

Right now, hard coded:
nQty = EVALUATE(tcAliasName + ".INSTOCK") + EVALUATE(tcAliasName + ".ONORDER") - EVALUATE(tcAliasName 
+ ".REORDERPNT")
If I place the entire hard-coded expression to a variable, as:
cExpr = 'EVALUATE(tcAliasName + ".INSTOCK") + EVALUATE(tcAliasName + ".ONORDER") - EVALUATE(tcAliasName  + ".REORDERPNT")'
Will the above work as?
nQty = EVALUATE( cExpr ) 
*-- or
nQty = &cExpr.
TIA
