ChrStartVariable

Syntax	ChrStartVariable <chr>
Description	A single-character key that triggers the creation of a variable. The key should match the first character in a field name. When this key is found in the input data, a variable $<field name> is created. Note that the key character is removed from the variable name.
Comments	You can also use the ChrStartVariable keyword instead. See LabelStartVariable. You can use either LabelStartVariable or ChrStartVariable – not both.
