Description
GS 0 prints a bit-image from storage in the nonvolatile memory pool. The
name of the bit-image can be from one to 15 bytes long and contain any
alphanumeric characters as well as spaces. GS . searches the nonvolatile
memory pool for the first occurrence of the image identified by <
name
>. If
the image is found, it will be printed. If the image cannot be found, this
command will be ignored. In standard mode, this command must be
entered at the beginning of a print line. In page mode, this command may
be entered at any time.
The following basic example demonstrates how to print the stored bit-
image named “MY IMAGE”:
PRINT #1, CHR$(29), CHR$(48),
REM Enter the GS 0 command
PRINT #1, “MY IMAGE”, CHR$(0)
REM Enter the image name
