UniBasic Commands Reference - Rocket Software

Parameters
The following table describes each parameter of the syntax.
Parameter Description
str.expr Specifies a UniData command with appropriate parameters. If
you pass a file name to PERFORM, you must use the actual file
name, not a file variable (which is assigned in the OPEN
statement).
ASYNC | SYNC UniData no longer supports this parameter, but it remains for
syntax compatibility.
ON connection UniData no longer supports this parameter, but it remains for
syntax compatibility.
ON ERROR statements UniData no longer supports this parameter, but it remains for
syntax compatibility.
CAPTURING,
dyn.array.var
RETURNING,
dyn.array.var
The CAPTURING clause stores the output in a dynamic array
instead of on the display terminal. Each line of the text becomes
an attribute in the array. Output sent to the printer is not affected
by this clause.
The order of CAPTURING and RETURNING is
interchangeable.
The RETURNING clause captures error messages resulting
from the command executed with PERFORM. This variable
contains a string of error message numbers separated by spaces.
If the executed command creates a spooler hold file, UniData
also returns the hold file number in the same variable.
EXECUTE Parameters
EXECUTE 1-267
