Introduction to HPSL
15
Program Line Terminators. A terminator informs HPSL that it has reached the end of a statement. Normally, this is sent
automatically by your GPIB programming statements. The termination also occurs with other terminator codes, such as
EOI. In this guide, the terminator is assumed at the end of each example line of code. If it needs to be indicated, it is shown
by the symbol < nl >, which stands for “new line”' and represents the ASCII coded byte 0A hexadecimal (or l0 decimal).
Common Commands
Common statements are not derived from HPSL but are generic commands and queries defined by the IEEE 488.2 standard.
The following examples are common statements:
• *RST
• *IDN?
• *TRG
Common statements are executed independently of HPSL statements. Their relationship to HPSL statements is described
more fully in “Chapter 3”. The function of each common statement is summarized in Chapter 4 - Language Dictionary and
fully described in Section 10 of IEEE 488.2 Standard Digital Interface for Programmable Instrumentation.
