CASE-END Executes a series of test-ciause commands that execute the

appropriate tme-clause sequence of commands. Its syntax is;

CASE

IF test-clause^ THEN true-clause^END

IF test-clause^ THEN true-clause^ END

END

When CASE is executed, tesUlause^ is evaluated. If the test is true,

tme-clause^ is executed, and execution skips to END. If tesKlause,

if false, execution proceeds to test-clause^. Execution with the

CASE structure continues until a true-clause is executed (or until

all the test-clauses evaluate to false).

Many conditions are automatically recognized by the HP 38G as

error conditions—and they’re automatically treated as errors in

programs.

IFERR...THEN...ELSE allows a program to intercept error

conditions that otherwise would cause the program to abort. Its

syntax is:

IFERR trap-clause

THEN error-clause ELSE normal-clause END

RUN

Runs the named program. If your program name contains

special characters, such as a space, and then you must enclose

the file name in double quotes (“ ")■

RUN "program name" or RUN programname

STOP

Stops the current program.

STOP
