Instructions
Type conversions can be performed with the INT, REAL, CMPLX, ITOL, and LTOI
DMAP functions.
For character assignment statements, if the length of the expression does not match the
size of the variable, the expression is adjusted as follows:
• If the expression is shorter than the variable, the expression is padded with
enough blanks on the right before the assignment takes place to make the
sizes equal.
• If the expression is longer than the variable, characters on the right are
truncated to make the sizes the same.
Function Statement
Functions can only appear within an arithmetic or logical expression; they cannot be
referenced within module or CALL statements. Execution of the function causes the
evaluation of the function and returns a value to the referencing expression. Some
functions, however, may appear as a DMAP statement without appearing in an
arithmetic or logical expression. These functions are DIAGON, DIAGOFF, NOOP,
PUTSYS, PUTDIAG, RDIAGOFF, and RDIAGON.
The type of the value returned from a function is dependent on the type of the
argument(s) supplied, in addition to the functional operation. In general, the precision
(single, double) and form (integer, real, complex) of the result returned by the function
carries at least as much information as the arguments supplied. For example,
ACOS(X) is typed as follows:
X ACOS(X)
I RS
RS RS
RD RD
CS CS
CD CD
Returned values for character functions can be processor dependent.
