10.1 SDF syntax description

This syntax description is based on SDF Version 4.1A. The syntax of the SDF command/ statement language is explained below in three tables.

Table 9: Metasyntax

Command and statement formats use certain characters and forms of representation; their meanings are described in Table 9.

Table 10: Data types

Variable operand values are represented in SDF by means of data types. Each data type represents a certain set of values. The number of data types is limited to the data types described in Table 10.

The description of data types is valid for all commands and statements, and operand descriptions describe only the deviations from Table 10.
