Common Service Verbs Reference
Overview
Chapter 240
Overview
This chapter contains a description of each of the Common Service Verbs.
The following information is provided for each verb:
• Definition of the verb.
• Structure defining theverb control block (VCB) used by the verb. The
structure is declared in the CSV header file.
• Parameters (VCB fields) supplied for and returned by the verb. For
each parameter, the following information is provided:
— Description
— Possible values
— Additional information
• Additional information describing the use of the verb.
Most parameters supplied with and returned by Common Service Verbs
are hexadecimal values. To simplify coding, these values are represented
by meaningful symbolic constants, which are defined in the CSV header
file. For example, the opcode (operation code) parameter for the
CONVERT verb is the hexadecimal value represented by the symbolic
constant SV_CONVERT.
It is important that you use the symbolic constant and not the
hexadecimal value when setting values for supplied parameters, or when
testing values of returned parameters. This is because different systems
store these values differently in memory, so the value shown may not be
in the format recognized by your system.
If you are writing applications for use in other environments as well as
SNAplus2, see “Writing Portable Applications”.
