PGL Programmer's Reference Manual

Emulation Switching

Purpose To switch the active emulation from IGP/PGL to the emulation

selected.

Mode NORMAL

Format (cc)EMULATION;

emulation

(cc) The Special Function Control Code.

EMULATION The Emulation Switch command. Enter

EMULATION.

emulation

Specifies the emulation to activate. Currently, the

only selection is VGL (Code V). Enter VGL. If VGL

is not the selection, this command is then ignored.

Comments This command is only processed when VGL is included in the

software package. If not, this command is simply ignored. The

switching of emulations causes IGP/PGL to perform a soft reset.

Therefore, front panel selections return to their factory default

state, and all forms and logos resident in RAM memory are

deleted.

End

Purpose Terminates the current mode of operation and must be used

before entering a new mode command (EXECUTE, LOGO,

NORMAL, or even CREATE).

Mode CREATE

Format END

Comments After the End command is received, the IGP/PGL flushes

program errors, stores the error-free portions of the form program

just completed, and then returns to the Normal mode. If the

debug slash (/) is included in the Create command, the program

prints with any corresponding error messages.
