fields, each followed by a varying number of numeric values, might be processed by statements
such as:
while data is not ended
until mode is alpha
do
read NUMBER
.
.
loop
stop
The property double is treated as synonymous with real, while text may be used as a
synonym for alpha.
5. Although free-form input in SIMSCRIPT II.5 ignores record columns or record boundaries,
it is possible to test whether the next data field is positioned at the beginning of a data
record. Perhaps this condition might indicate the start of a new batch of data items. The
condition may be tested for by such logical comparisons as:
if card is not new
until card is new
When there are no further data fields (either none exists or all data have been read and lookahead
is impossible), the system variables have the values shown in table 2-5.
Note: The term card is used for historical reasons . It stands for record.
