Labels are typically targets for branching ('jump') Instructions. A Label is distinguished from an
Instruction by starting with the '@' character and ending with a colon (':'), for example:
@MYLABEL:
Labels may be on a line on their own, or may precede one or more Instructions on the same line.
Comments may be added to the segment definitions in two ways; enclosed within '/*' and '*/' delimiters
or with the '//' form which defines a Comment that lasts to the end of a line:
/* This is a comment */ JUMP(@start)
// So is this, anything on this line is ignored from here
Comment text is ignored by the compiler and serves only to make a Test Sequence source file easier
to read.
6.2 Language reference
This section details the use of all Test Sequence keywords.
Sequence Start and End
A HEADER Instruction MUST be the first Instruction in the source file. It defines the start of the Test
Sequence, and includes a 16 character text message that appears on the DSA-1 display when the
Sequence is selected or run, for example:
HEADER('Special Test ')
Similarly, the final Instruction of the Sequence should be:
END
Segment Start and End
These Instructions define the beginning and end of a Segment (the concept of a Test Sequence
Segment is described above). Here is an example of a Segment start Instruction; the first parameter
defines the running-order position of the Segment, the second is a message to be displayed when the
segment runs or fails:
SEGMENT( 3, 'fs Tests ')
The Segment end instruction has no parameters and causes the DSA-1 to skip to the beginning of the
next segment, or to end the sequence if there are no more Segments (or if the Segment has failed):
SEGMENT_END
Set switches
These Instructions have no parameters and are used to set the DSA-1 switched operating
parameters:
