For pTAL and TAL
PAGE
The first PAGE prints a heading (if any) on the compiler listing, skips a line, and
continues printing. Each subsequent PAGE prints a heading (if any) and causes a
page eject.
heading-string
is a character string whose maximum length is 82 characters in TAL and 122
characters in pTAL.
WARN
WARN suppresses compiler warning messages.
TAL and pTAL warning numbers are disjoint. Warning numbers from 0 through 64 are
TAL warnings and are ignored by the native compiler, except for the following numbers,
which are mapped to their pTAL equivalents:
The native compiler converts the preceding TAL warning numbers into their equivalent
pTAL warning numbers and suppresses or enables printing of the equivalent pTAL
warning.
If warning-number is outside the range of all pTAL warnings and all TAL warnings,
the native compiler issues a warning. If warning-number is inside either range but
not assigned warning text, the compiler ignores the WARN directive.
