BAD VOLUME NAME
A disc volume name must begin with a dollar sign followed by a letter,
may contain only letters and numerals in the rest of the name, and may not
exceed a total of eight characters. An identifier that violates one or more of
these rules appeared in a place where a volume name was expected.
COMMAND ERROR
A trigger character in the first character position of an input line was
followed by an identifier that doesn’t resemble any known TFORM
command or macro name.
COMMAND OUT OF PLACE
A command that TFORM expects to see in a specific place has appeared
elsewhere; for example, an ELSE command outside of an IF construct or an
EXITMACRO not in a macro. This error can also be caused by an earlier
error in the command (IF, MACRO BEGIN, and so on) that should have
created the context in which the supposedly erroneous command was
expected to appear.
COULD NOT OPEN INPUT FILE, ERROR CODE file-error-number
A SOURCE command failed because it couldn’t open the chosen file. The
accompanying GUARDIAN 90 file system error number displays the cause.
DUPLICATE MACRO/FUNCTION - CONFLICTING NAME: macro/function-name
A MACRO macro-name BEGIN or a FUNCTION function-name BEGIN
command contained the name of an existing macro, function, or the name
of a TFORM command.
