Procedure
SYDIMC ( Return the dimension of a symbol )
INTEGER FUNCTION SYDIMC ( NAME, TABSYM, TABPTR, TABVAL )
Abstract
Return the dimension of a particular symbol in a character symbol
table. If the symbol is not found, the function returns the value
zero.

Brief_I/O
VARIABLE I/O DESCRIPTION
-------- --- --------------------------------------------------
NAME I Name of the symbol whose dimension is desired.
TABSYM,
TABPTR,
TABVAL I Components of the symbol table.
The function returns the dimension of the symbol NAME. If NAME is
not in the symbol table, the function returns the value zero.
Detailed_Input
NAME is the name of the symbol whose dimension is to be
returned. If the symbol is not in the symbol table, the
function returns the value zero. This function is case
sensitive, NAME must match a symbol exactly.
TABSYM,
TABPTR,
TABVAL are the components of a character symbol table. The table
may or may not contain the symbol NAME.
Detailed_Output
The function returns the dimension of the symbol NAME. The
dimension of a symbol is the number of values associated with
that symbol. If NAME is not in the symbol table, the function
returns the value zero.
Parameters
None.
Exceptions
None.
Files
None.
Particulars
None.
Examples
The contents of the symbol table are:
BOHR --> HYDROGEN ATOM
EINSTEIN --> SPECIAL RELATIVITY
PHOTOELECTRIC EFFECT
BROWNIAN MOTION
FERMI --> NUCLEAR FISSION
Perhaps we want to know how many subjects are associated with
certain scientists. The following code returns the values of
NUMSUB indicated in the table.
NUMSUB = SYDIMC ( 'EINSTEIN', TABSYM, TABPTR, TABVAL )
NUMSUB = SYDIMC ( 'BOHR', TABSYM, TABPTR, TABVAL )
NUMSUB = SYDIMC ( 'FERMI', TABSYM, TABPTR, TABVAL )
NUMSUB = SYDIMC ( 'MILLIKAN', TABSYM, TABPTR, TABVAL )
----SYMBOL----------NUMSUB------
| EINSTEIN | 3 |
| BOHR | 1 |
| FERMI | 1 |
| MILLIKAN | 0 |
