Syntax: ISSTR
(VAR)
Parameter:
VAR Name of the variable whose data type is to be
checked.
FALSE =
TRUE =
The result of the scan can be:
numerical variable (data type = REAL)
not
a numerical variable (data type = STRING)
Example:
IF ISNUM(VAR1) == TRUE
IF ISSTR(REG[4]+2) == TRUE
The display mode of variables can be changed:
●
For INTEGER, the display type can be changed.
B Binary
D Decimal signed
H Hexadecimal
unsigned
With the addition of U for Unsigned
● For REAL data types, only the number of places after the decimal point can be changed.
Changing
the type is illegal and generates an error message in the easyscreen_log.txt. file.
Example:
Var1.typ = "IBW"
Var2.typ = "R3"
Numerical formats
Numbers can be represented in either binary, decimal, hexadecimal or exponential notation:
Binary B01110110
Decimal 123.45
Hexadecimal HF1A9
exponential -1.23EX-3
Examples:
VAR1 = HF1A9
REG[0]= B01110110
DEF VAR7 = (R//-1.23EX-3)
Note
When codes are generated with the "GC" function, only numerical values in decimal or
exponential notation are evaluated, but not those in binary or hexadecimal notation.
