B.3 String Commands

String commands (in a Process block) are used to manipulate strings and String

tags.

NOTE: All String outputs are NULL-terminated.

B.3.1 String Copy

This command can be selected from the String commands list.

When used in a Flow Chart, the String Copy commands directly copies one String

into another.

Parameters for this command include:

 Destination String – The String tag to which the Source String will be

copied.

To configure the Destination String parameter, click the

button to

open a standard Select String Tag dialog.

NOTE: If the defined length of the Destination String is not long enough

to receive the result of the command, then the output will be truncated.

No error will be generated.

 Source String – The string to be copied into the Destination String.

The value of Source String may be a String tag, a literal string enclosed in

single quotes (‘ ’), or some other logical expression that is evaluated every

time the block is executed.

To configure the Source String parameter, click the

button to open a

standard Build String Argument dialog.

NOTE: Source String is not modified by the execution of this command.
