Reading Integers works, reading strings don't work:

Code: Select all

Structure xx
t1.a
t2.s
t3.i
t4.i
t5.s
EndStructure

xx.xx
xx\t1 = 5
xx\t2 = "text"
xx\t3 = 50
xx\t4 = 123456
xx\t5 = "other"

Debug PeekA(xx + OffsetOf(xx\t1))
Debug PeekS(xx + OffsetOf(xx\t2))
Debug PeekI(xx + OffsetOf(xx\t3))
Debug PeekI(xx + OffsetOf(xx\t4))
Debug PeekS(xx + OffsetOf(xx\t5))

PeekS() expects the address of the actual text, not the string variable.

Code: Select all

Structure xx
t1.a
t2.s
t3.i
t4.i
t5.s
EndStructure

xx.xx
xx\t1 = 5
xx\t2 = "text"
xx\t3 = 50
xx\t4 = 123456
xx\t5 = "other"

Debug PeekA(xx + OffsetOf(xx\t1))
Debug PeekS(PeekI(xx + OffsetOf(xx\t2)))
Debug PeekI(xx + OffsetOf(xx\t3))
Debug PeekI(xx + OffsetOf(xx\t4))
Debug PeekS(PeekI(xx + OffsetOf(xx\t5)))

The address of PB strings are stored in the Structure. If you want strings directly in the Structure, then use a byte or char array.

Code: Select all

Structure xx
t1.a
t2.s
t3.i
t4.i
t5.s
EndStructure
xx.xx
xx\t1 = 5
xx\t2 = "text"
xx\t3 = 50
xx\t4 = 123456
xx\t5 = "other"
Debug PeekA(xx + OffsetOf(xx\t1))
Debug PeekS(PeekI(xx + OffsetOf(xx\t2)))
Debug PeekI(xx + OffsetOf(xx\t3))
Debug PeekI(xx + OffsetOf(xx\t4))
Debug PeekS(PeekI(xx + OffsetOf(xx\t5)))

or a fixed string.

Code: Select all

Structure xx
t1.a
t2.s{20}
t3.i
t4.i
t5.s{20}
EndStructure

xx.xx
xx\t1 = 5
xx\t2 = "text"
xx\t3 = 50
xx\t4 = 123456
xx\t5 = "other"

Debug PeekA(xx + OffsetOf(xx\t1))
Debug PeekS(xx + OffsetOf(xx\t2))
Debug PeekI(xx + OffsetOf(xx\t3))
Debug PeekI(xx + OffsetOf(xx\t4))
Debug PeekS(xx + OffsetOf(xx\t5))
