Naming Guidelines for Local Variables
The names that you give to local variables must follow the standard naming conventions. The following naming guidelines also apply to local variables:
• A general convention is to begin the name of a local variable with "h_" to designate it as hidden field; for example, h_date in the example above.
• The name of a local variable can be up to 65 characters in length.
• For a hidden column in a table field, include the table-field name at the beginning of the local variable name; for example, detailtbl.h_custno.
• Do not begin any variable names with the string "ii", because this prefix is reserved for use by Ingres. Vision adds the string "iih_" to the beginning of all variable names when it generates the code for a frame.
• A local variable cannot have the same name as a displayed column in the Master or Detail table used for this frame.
• You can define a local variable with the same name as a non-displayed column in the Master or Detail table (except for a non-displayed column with an assigned value on an Append frame).
• A local variable cannot have the same name as a local procedure.
