trim Function

The trim function removes any unnecessary white space surrounding a parameter. The syntax for the trim operation is:

variableA=trim(parameter)

where:

variableA identifies the variable

parameter is the item from which white space must be removed

For example, if you decompose an alias list into its constituent members, you could define the following variables:

aliasMember=string2instances($aliasList, ",")
trimAliasMember=trim($aliasMember)

Each aliasMember parameter resulting from the string2instances operation is processed to remove any white spaces.
