Symbol Meaning Example

< precedes alphabetically

"A" < "B"

> follows alphabetically

"JOE" > "JIM"

= equals

B$= "WIN"

does not equal

IF A$<>B$ THEN PRINT A$

precedes or equals

IF A$<=AZ$ PRINT "DONE"

follows or equals

IF L1$>="SMITH" PRINT L1$

+ concatenate the two

strings

A$ = C$+C1$

A$ = "TRS-"+"80"

Determining the type of a constant

The following rules determine how a constant and typeOmatic variables are typed:

I. If a constant contains 10 or more digits, or if D is used in the

exponent, that number is double precision. Adding a #

declaration character also forces a constant to be double

precision.

II. If the number is not double-precision, and if it contains a decimal point , then

the number is float. If number is expressed in exponential

notation with E preceding the exponent, the number is float

III. If neither I nor II is true of the constant, then it is an integer.
