Abbreviations of function names must follow certain rules. For some functions, a fixed abbreviation is defined as an alias; it is specified in the syntax representation as a shorter name.
Example
SUBSTRING( ) SUBSTR( ) |
The function can be called either with the name SUBSTRING or SUBSTR.
Parameter names can be abbreviated as long as they remain unique.
An abbreviation in the format “parameter=” is not possible. The entry is rejected.
Keywords can be abbreviated to the point of uniqueness in accordance with the SDF abbreviation rules. The following points must be noted:
The abbreviation may no longer be unique in later SDF-P versions, if there are new keywords with the same abbreviation options. For this reason, you should try to abbreviate less than what is allowed.
Procedures should be kept straightforward and easy to read, i.e. it is not always a good idea to abbreviate names to their shortest possible form.
