11-132

TANDEM

specifies that subsequent source text is in Tandem reference format, which is

described in Reference Format for Source Program Lines.

ANSI

specifies that subsequent source text is in ANSI reference format, which is

described in Section 16, ANSI Reference Format.

TRAP2 and NOTRAP2

TRAP2

specifies that the compiler expects the operating environment to trap arithmetic

overflow (trap 2). (By default, the COBOL85 compiler expects this and the

HP COBOL 74 compiler does not.)

Default: TANDEM

Placement: Anywhere

Scope: TANDEM or ANSI within a section of text obtained from a copy library or

source library is effective only for the length of that text section. When

the compiler reverts to the source file where it found the COPY verb or

SOURCE directive, the previously active reference format applies.

Dependencies: None

References: ANSI

Note. The NMCOBOL compiler, which has traps set by default, ignores these directives and

issues warnings.

Use the NOTRAP2 directive only during the process of conversion from COBOL 74 to

HP COBOL. It is provided to enable programs that do not include SIZE ERROR phrases to be

compiled and executed in HP COBOL without investing programmer time in analyzing the

potential for overflow problems. The availability of this directive might be discontinued.
